The chiral building block (R)-(+)-2,2 ‘-diamino-1,1 ‘-binaphthyl, (R)-BINAM, which is often used as backbone in privileged enantioselective catalysts, was converted to a series of N-substituted proligands (R)1-H-2 (R = CH(2)tBu, C(H)Ph-2, PPh2, dibenzosuberane, 8-quinoline). After double deprotonation with strong Mg or Ca bases, a series of alkaline earth (Ae) metal catalysts (R)1-Ae.(THF)(n) was obtained. Crystal structures of these C-2-symmetric catalysts have been analyzed by quadrant models which show that the ligands with C(H)Ph-2, dibenzosuberane and 8-quinoline substituents should give the best steric discrimination for the enantioselective intramolecular alkene hydroamination (IAH) of the aminoalkenes H2C = CHCH2CR ‘ 2CH2NH2 (CR ‘(2) = CPh2, CCy or CMe2). The dianionic (R)1(2-) ligand in (R)1-Ae center dot(THF)(n) functions as reagent that deprotonates the aminoalkene substrate, while the monoanionic ((R)1-H)(-) ligand formed in this reaction functions as a chiral spectator ligand that controls the enantioselectivity of the ring closure reaction. Depending on the substituent R in the BINAM ligand, full cyclization of aminoalkenes to chiral pyrrolidine products as fast as 5 minutes was observed. Product analysis furnished enantioselectivities up to 57% ee, which marks the highest enantioselectivity reported for Ca catalyzed IAH. Higher selectivities are impeded by double protonation of the (R)1(2-) ligand leading to complete loss of chiral information in the catalytically active species.

In this article, we describe the development of a new aerobic C-H oxidation methodology catalyzed by a precious metal-free LaMnO3 perovskite catalyst. Molecular oxygen is used as the sole oxidant in this approach, obviating the need for other expensive and/or environmentally hazardous stoichiometric oxidants. The electronic and structural properties of the LaMnO3 catalysts were systematically optimized, and a reductive pretreatment protocol was proved to be essential for acquiring the observed high catalytic activities. It is demonstrated that this newly developed method was extremely effective for the oxidation of alkylarenes to ketones as well as for the oxidative dimerization of 2-naphthol to 1,1-binaphthyl-2,2-diol (BINOL), a particularly important scaffold for asymmetric catalysis. Detailed spectroscopic and mechanistic studies provided valuable insights into the structural aspects of the active catalyst and the reaction mechanism.

A new aromatic diamine, 10,10-bis [4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthracenone (BAPPA) was synthesized from anthrone as the starting material, and the corresponding pyridine- and anthrone-containing poly(ether amide)s (PEAs) were prepared from BAPPA with various aromatic diacid chlorides via a low-temperature solution polycondensation. The resulting PEAs having number-average molecular weights (M-n) of 29,500-33,400 g/mol with the polydispersity index ranged from 1.75 to 1.84, were all amorphous, and displayed excellent thermal stability with the glass transition temperatures of 263-355 degrees C, the temperatures of 415-441 degrees C at 5% weight loss and the higher than 50% residues at 800 degrees C in nitrogen. These new PEAs were soluble in polar solvents such as N-methyl-2-pyrrolidone, N,N-dimethylacetamide and pyridine, even almost in tetrahydrofuran at room temperature and could form transparent, strong and flexible films with tensile strengths of 84-97 MPa, tensile moduli of 2.1-3.2 GPa and elongations at break of 4-13%. Also, the present PEAs exhibited high optical transparence with the UV cutoff wavelength in the 342-362 nm range, and 83-90% transmittance at 500 nm. These results indicated the introduction of anthrone and pyridine groups into the backbone could improve the solubility and transparence of polyamides.

An environmentally friendly, inexpensive, carbocatalyst, graphene oxide (GO) promoted efficient, metal-free transamidation of various carboxamides with aliphatic, cyclic, and aromatic amines is demonstrated. The protocol is equally applicable to phthalimide, urea, and thioamide determining its adaptability. The oxygenated functionalities such as carbonyl (C=O), epoxy (O), carboxyl (COOH) and hydroxyl (OH), present on graphene oxide surface impart acidic properties to the catalyst. The graphene oxide being heterogeneous in nature, work efficiently under solvent-free reaction conditions providing desired products in good to excellent yields. The one-pot synthesis of 2,3-Dihydro-5H-benzo[b]-1,4-thiazepin-4-one moiety by GO catalyzed Aza Michael addition followed by intramolecular transamidation is also described. A plausible reaction mechanistic pathway involving H-bonding is discussed. The graphene oxide can be recycled and reused up to five cycles without much loss in catalytic activity.

Polycyclic aromatic hydrocarbons (PAHs) are mutagenic and carcinogenic. 16 PAHs as priority pollutants listed by the US Environmental Protection Agency were usually monitored. Therefore, multiple potentially toxic polycyclic aromatic compounds (PACs) are not monitored. In this study, atmospheric particulate matter samples from Beijing were analyzed using atmospheric pressure photoionization (APPI) Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry and comprehensive two-dimensional gas chromatography-time-of-flight (GC x GC-TOF) mass spectrometry. The FT-ICR data detected high molecular weight PAHs, alkylated PAHs (APAHs) and heteroatom PAHs. The GC x GC-TOF data tentatively identified 386 PACs in five categories of identification confidence. Twenty-one spectra in the unknown class were manually resolved. Eighty-two PACs with high identification confidence were proposed for further research. The identities of five PAHs and five APAHs that are currently not regulated were confirmed using available standards and quantified in some samples. Some of these PACs, such as dibenzo[a,e]pyrene (C22H14) and 1-methylpyrene (C17H12), should be of concern because of their contamination levels and the high toxicities of themselves and/or their derivatives. This study highlights the possibility of expanding the traditional lists of PAHs to improve pollution control and risk assessment accuracy.

Using green chemical method a series of fifteen systematically substituted 3-(9-substituted anthracen-10-yl)-1-(4-phenyl substituted)prop-2-en-1-one derivatives having high nonlinear absorption coefficient have been synthesized. The nonlinear absorption properties of these compounds were studied using nanosecond pulses at 532 nm wavelength. All 15 derivatives are found to show high nonlinear absorption in the range of 35-640 cm/GW. Among these the derivatives with-NO2 as one of the substitution group show higher nonlinear absorption. The origin of high nonlinear absorption with low linear absorption in the compounds has been attributed to two-step two-photon absorption process. We have shown that the energy bands of these compounds are distributed such that for excitation at 532 nm they have strong nonlinear absorption. These properties of the reported compounds make them a potential candidate for biological imaging and other applications which are based on nonlinear absorption. (C) 2020 Elsevier B.V.

Herein, we report on the highly efficient and practical synthesis of 2,3-dihydroquinazolinones directly from diverse aldehydes with excellent yields and enantioselectivity. Particularly, this protocol affords better enantiocontrol for aliphatic aldehydes (up to 99% yield, 97% ee), which always gave unsatisfactory results in the previous studies. Moreover, this catalytic system shows wide tolerance to different functional groups such as alkenyl, nitro and halogens. Most importantly, its practicability is well elucidated via the gram-scale synthesis of different types of products at 0.1 mol% catalyst loading and the simplified work-up procedure. To better understand the reaction pathway and origin of the enantioselectivity, DFT calculations were also performed.

A series of novel tricyclic quinazolinone-iminosugars 1 (a-c) were synthesized from the benzyl protected sugars through three steps. Firstly, the benzyl protected sugar (aldehyde) 5 reacted with o-aminobenzamide by the iodine-induced oxidative condensation to afford the corresponding aldo-quizanolinone 6. Secondly, through the intramolecular cyclization of the unprotected OH and the amide NH in 6, the tricyclic compounds 7 and 8 were constructed by the key Mitsunobu reaction. Finally, removal of the benzyl group gave the target tricyclic quinazolinone-iminosugars 1. The protocol was effective for the preparation of the tricyclic iminosugars in satisfactory yield. Interestingly, an unusual C-2 epimerization was observed with D-mannose and D-ribose compounds under the conditions of the Mitsunobu reaction that generated the products having the trans configuration at the C-2 and C-3 positions. Unfortunately, such tricyclic quinazolinone-iminosugars showed no inhibitory effects on the tested five glycosidases.
