Group 6 alkynyl Fischer carbene complexes behave as electrophiles with highly reactive masked dienes such as anthrone and 3-hydroxy-2-pyrone, which also can react as bidentate nucleophiles. Both Cr-0 and W-0 alkynyl carbene complexes require tertiary amines to promote the formation of 1,4-C-addition products, but a marked dependence of the reactivity on the metal was observed. Although W-0 complexes form exclusively the 1,4-C-adducts in the presence of a catalytic amount of base, Cr-0 complexes lead to new anthrone-derived bis-carbene complexes, obtained by a sequential 1,4-C- and 1,4-O-addition process with high diastereoselectivity and only in the presence of an excess of base. DFT computational studies show that the gap between the LUMO of the complex and the HOMO of the anthrone determines the differences in reactivity and that the stability of the intermediate metal allenyls formed after the initial 1,4-addition is decisive for the outcome of the reaction.

This study included 1456 men and 1411 women who were trauma-exposed and underwent routine health examinations in a community epidemiological investigation. The participants completed the posttraumatic stress disorder (PTSD) Check List-Civilian Version (PCL-C) for PTSD and medical examinations to detect metabolic syndrome. Adjustments for age, marriage, exercise, education, cigarette smoking, cancer, stroke, angina, and thyroid disease were performed. The relationship between PTSD and metabolic syndrome and each of its components was analyzed by multiple logistic regression. In women, PTSD was associated with metabolic syndrome (OR = 1.53, 95% CI = 1.01-1.95, P = .047) and the high-density lipoprotein cholesterol component (OR = 1.98, 95% CI = 1.04-2.12, P = .002). In men, PTSD was related to the hypertension component of metabolic syndrome (OR = 0.54, 95% CI = 0.31-0.92, P = .023). There was also a relationship between PTSD severity and metabolism (OR = 1.141, 95% CI = 1.002-1.280, P = 0.037) in women, and PTSD was inversely associated with the hypertension component (OR = 0.54, 95% CI = 0.31-0.92, P = .023) in men. PTSD was related to metabolic syndrome only in women. We plan to further research the mechanism of sex differences and dyslipidemia.

Thioamides could be conveniently synthesized in good to excellent yields via DMSO-promoted oxidative coupling of methylhetarenes with amines in the presence of a near stoichiometric amount of sulfur (1.25 equiv.). Both aliphatic and aromatic amines were found to be competent substrates. When anilines o-substituted by cyclizable groups such as OH, NH2, NHPh, SH and CONH2 were used as amine substrates, the corresponding hybrid bis-aza-heterocycles were formed in high yields even with a sulfur loading as low as 0.5 equiv.

The impact of volatile organic compounds (VOCs) and odor on indoor environment and people has attracted much attention. To reduce this problem of odorous compounds contained in wood panel, this study focused on identifying odorant compounds and exploring the influence of moisture content factors on VOCs and odor emissions. Paper mulberry (Broussonetia papyrifera (L.)Vent.) was investigated using the technology of gas chromatography-mass spectrometry/olfactory (GC-MS/O). Total volatile organic compounds (TVOC) and characteristic odor-active compounds were studied, and the emission of heartwood and sapwood of paper mulberry was compared at the same time. It was found that the main components from heartwood and sapwood were aromatics, alkanes, alkenes, aldehydes ketones, alcohols and esters. Totally, 23 kinds of odor-active compounds were identified from heartwood and sapwood of paper mulberry, among which, aromatics and aldehydes ketones were the main odorant compounds. Seven kinds of key odorant compounds were identified in this process. With the decrease in moisture content, the TVOC and total odor intensity of heartwood and sapwood generally decreased. The moisture content had a great effect on VOC release when the moisture content decreased from 70 to 50% and reduced from fiber saturation point (30%) to air saturation point (10%). The main odor impressions of paper mulberry were aromatic, fresh fruit fragrance, sweet scent and special pungent. In the whole process of moisture content decrease, the TVOC, concentration of odorant and odor intensity of sapwood were higher than that of heartwood.

Fluorescent materials with a large enough Stokes shift (>100 nm) have widely prospect in light conversion agricultural film, cell-imaging, chemosensory and so on. However, most of traditional fluorescent dyes displayed small Stokes shifts which severely limited their application. In this paper, a side-chain alternative copolymer named P(DMPNI-alt-TPE) was developed, in which the two fluorophores were next to each other: the AIE-active tetraphenylethene (TPE) acted as energy donor, while naphthalimide derivative (DMPNI) with intramolecular charge transfer (ICT) character as energy acceptor. Attributed to this unique structure, the copolymer combined efficient dark/fluorescence resonance energy transfer (DRET/FRET) and polarity-sensitivity. And therefore it showed impressive large pseudo-Stokes Shift up to 304 nm and 302 nm in solution and aggregative state respectively. Interestingly, this copolymer exhibited a V-shaped fluorescence variation curve in a series of THF solutions with increasing fraction of water. Moreover, P(DMPNI-alt-TPE) emitted different color fluorescence in various solvents upon UV light, so that its pseudo-Stokes shift was not only large but also tunable, and the changing range was from 262 to 304 nm. Lastly, the potential possibility of P(DMPNI-alt-TPE) as light conversion agricultural film was investigated. This research provided a new approach for the development of fluorescence materials with large and tunable Stokes shift.

The volatile compounds of Jiaozi-steamed breads (JSBs) fermented by Jiaozi starters from eight regions in China were extracted using simultaneous distillation and extraction (SDE) and headspace solid-phase microextraction and determined using gas chromatography-mass spectrometry (GC-MS). 1-Hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid were the main volatiles of JSBs. Principal component analysis exhibited that the volatiles of JSBs from Nanyang City, Xi’an City, and Zhumadian City was negatively correlated to that of other five JSB samples. Cluster analysis demonstrated that the volatile characteristics of JSBs from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City belonged to a category, and the JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. It demonstrated that the volatile components of steamed breads in North China and South China were different. Practical applications From this study, it can be seen that simultaneous distillation and extraction (SDE) can completely extract volatile compositions of steamed breads fermented by Chinese traditional starter Jiaozi. SDE/GC-MS was suitable for the analysis of JSBs volatile composition. The relative contents of 1-hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid in JSBs were at high level, and their contents could be used as a marker to identify JSBs. The volatile compositions of JSBs made of Jiaozi starters from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City were similar. However, JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. The volatile components of steamed breads in North China and South China were different, which reflected the difference in dietary habit in the southern and northern areas of China.

Wildfires have become more common and intense in the western US over recent decades due to a combination of historical land management practices and warming climate. Emissions from large-scale fires now frequently affect populated regions such as the San Francisco Bay Area during the fall wildfire season, with documented impacts of the resulting particulate matter on human health. Health impacts of exposure to wildfire emissions depend on the chemical composition of particulate matter, but the molecular composition of the real biomass burning organic aerosol (BBOA) that reaches large population centers remains insufficiently characterized. We took PM2.5 (particles having aerodynamic diameters less than or equal to 2.5 mu m) samples at the University of California, Berkeley campus (similar to 60 km downwind of the fires) during the October 2017 Northern California wildfires period and analyzed molecular composition of OA using a two-dimensional gas chromatography coupled with high-resolution time-of-flight mass spectrometry (GCxGC HR-ToF-MS). Sugar-like compounds were the most abundant component of BBOA, followed by mono-carboxylic acids, aromatic compounds, other oxygenated compounds, and terpenoids. The vast majority of compounds detected in smoke have unknown health impacts. Regression models were trained to predict the saturation vapor pressure and averaged carbon oxidation state ((OSc) over bar) of detected compounds. The compounds speciated have a wide volatility distribution and most of them are highly oxygenated. In addition, time series of primary BBOA tracers observed in Berkeley were found to be indicative of the types of plants in the ecosystems burned in Napa and Sonoma, and could be used to differentiate the regions from which the smoke must have originated. Commonly used secondary BBOA markers like 4-nitrocatechol were enhanced when plumes aged, but their very fast formation caused them to have similar temporal variation as primary BBOA tracers. Using hierarchical clustering analysis, we classified compounds into seven factors indicative of their sources and transformation processes, identifying a unique daytime secondary BBOA factor. Chemicals associated with this factor include multifunctional acids and oxygenated aromatic compounds. These compounds have high (OSc) over bar, and they are also semi-volatile. We observed no net particle-phase organic carbon formation, which indicates an approximate balance between the mass of evaporated organic carbonaceous compounds and the addition of secondary organic carbonaceous compounds.

The one-pot synthesis of quinazoline-2,4-diones was developed in the presence of 4-dimethylaminopyridine (DMAP) by metal-free catalysis. The commercially available (Boc)(2)O acted as a key precursor in the construction of the 2-position carbonyl of quinazolinediones. The p-methoxybenzyl (PMB)-activated hetero- cyclization could smoothly proceed at room temperature instead of the microwave condition. This strategy is compatible with a variety of substrates with different functional groups. Furthermore, this protocol was utilized to smoothly prepare Zenarestat with a total yield of 70%.

This is the first report on a facile tandem route for synthesizing quinazolinones at room temperature from various aminobenzamides and in situ-generated aldehydes. The latter was formed via C=C bond cleavage, and the overall reaction proceeded using molecular oxygen as a clean oxidant in the absence of a photocatalyst. Visible light, which was indispensable for the entire course of the reaction, played multiple roles. It initially cleaved styrene to an aldehyde, then facilitated its cyclization with an o-substituted aniline, and finally promoted the dehydrogenation of the cyclized intermediate. The previous step provided the feedstock for the next step in the reaction, thereby preventing volatilization, oxidation, and polymerization of the aldehyde. Thus, the overall process is simple, environmentally benign, and economically feasible.
