Interaction of morpholine and thiomorpholine with molecular diiodine: X-ray crystal structure of morpholinium triiodide

The reactions between the donors morpholine (1) and thiomorpholine (2) with I-2 in low polar solvents (C6H6, CHCl3, CH2Cl2) and different donor/I-2 concentration ratios (1:1, 1:2, 1:3) yield solids of stoichiometry 1 . I-2, 1H(+)I(3)(-), 1H(+)I(5)(-), 2 . I-2, and 2H+I-3(-). Crystals suitable for X-ray structure determination have been obtained only for 1H+I-3(-). All the solids were characterized by FT-Raman and FT-IR spectroscopies in the region ofthe v(I-I) frequencies. Studies in solution have been carried out on each of the reactions between 1, 2, and N-methylmorpholine (3) with I-2. The formation constants of the 1:1 adducts of 2 and 3 determined at 20 degrees C by UV-visible spectroscopy are 8500 and 8400 dm(3) mol(-1), respectively. IR spectroscopy shows that I-2 binds the nitrogen of 1 and 2 both in axial and equatorial positions. Further FT-Raman and C-13 NMR spectroscopies support the nature of weak adducts berween 1 (2) and the molecular diiodine in solution. (C) 1997 John Wiley & Sons, Inc.

Cobalt(III) complexes with a tetraaza macrocyclic ligand and some heterocyclic dithiocarbamates

Four new cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2), where cyclam and Rdtc(-) refer to 1,4,8,11-tetraazacyclotetradecane and 2-, 3-, 4-methylpiperidine (2-, 3-, 4-wMeepipdtc(-)) or 4-thiomorpholine (Timdtc(-)) dithiocarbamates, respectively, have been prepared. Elemental and thermal analyses, VIS, IR and H-1 and C-13 NMR spectroscopy have been used to characterized them. In the complexes, cobalt is hexa-coordinated in an octahedral geometry of a folded macrocyclic ligand and dithiocarbamates are bound as bidentates. As regards to the influence of the position of the methyl group on the piperidine ring, the nu(C – N) and nu(C – S) values increase in the order 2-Mepipdtc(-) < 3-Mepipdtc(-) < 4-Mepipdtc(-). Furthermore, the position of the methyl substituent also influences the thermal stability of the complexes and the order of stability decreases in the opposite order.

H-1 NMR: a tool to study the fate of pollutants in the environment

In situ H-1 NMR, directly performed on biological fluids is a very powerful tool to study the fate of pollutants in the environment. The biodegradation of 2-aminobenzothiazole by Rhodococcus rhodochrous was monitored by reverse phase HPLC and by in situ H-1 NMR, methods performed directly on culture media without purification. The xenobiotic was biotransformed into a hydroxylated derivative. The chemical structure of this metabolite was determined by a long-range H-1-N-15 heteronuclear shift correlation without any previous N-15 enrichment of the compound. This approach allowed the assignment of the metabolite structure to 2-amino-6-hydroxybenzothiazole. (C) 2001 Academie des sciences/Editions scientifiques et medicates Elsevier SAS.

Electrochemical examination of mixed-ligand cobalt(III) complexes with tetraazamacrocyclic ligand and heterocyclic dithiocarbamates

Electrochemical stability of eight complexes of the general formula [Co(III)Rdtc(1-8)cyclam](ClO4)(2), where cyclam = 1,4,8,11-tetraazacyclotetradecane and Rdtc(-) (1-8) = 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), 4-piperazine (Pzdtc), N-methyl piperazine (N-Mepzdtc), piperidine (Pipdtc), 2-, 3- or 4-methylpiperidine (2-, 3- or 4-Mepipdtc) dithiocarbamates, respectively, were studied. The substances were examined in aqueous NaClO4 solution and nonaqueous LiClO4 in CH3CN solution by cyclic voltammetry. In aqueous solution, macrocyclic ligand cyclam is characterized by the anodic peak at 0.95 V. The Rdtc(-) ligands have two anodic peaks, one in the region 0.25-0.30 V and the other in the 0.78-0.95 V region. Absence of these anodic peaks in the case of the complexes indicates that coordination to cobalt(III) stabilizes both cyclam and Rdtc(-) ligands, but reversible peaks in the range -0.68 to -0.78 V support the Co(III) redox reaction. In nonaqueous solutions cyclam has one anodic peak at 1.75 V. The ligands with heteroatom in the ring (Morphdtc, Timdtc, Pzdtc, N-Mepzdtc) have two anodic peaks, while the other four ligands (Pipdtc, 2-, 3- and 4-Mepipdtc) have only one anodic peak. In nonaqueous solution again, coordination to Co(III) ion stabilizes the Rdtc(-) ligands and contrary to aqueous solution no Co(III) redox reaction occurs, indicating a greater stability of the complexes in this media. Finally, the electrochemical results are compared with spectroscopic data obtained previously.

Nitrosation of 2-hydroxyethylpiperidine

The kinetics of the nitrosation of 2-hydroxyethylpiperidine have been studied in acidic (0.05-0.30 mol dm(-3) HClO4) aqueous media. The reaction rate is first order with respect to nitrite and amine and independent of acidity and shows an experimental isotope effect of 1.73. The most plausible mechanism involves the fast formation of an alkyl nitrite in the protonated amine (equilibrium constant estimated as 0.014 dm(3) mol(-1)). The loss of a proton from this intermediate is the rate-limiting step, and it is followed by a fast internal nitroso group transfer from the oxygen to the nitrogen atom to give the corresponding N-nitroso compound. A comparison of this nitrosation pathway of secondary amines in acid media with the nitrosation of thiomorpholine and piperidine, and with that of amines by alkyl nitrites in basic media is also discussed.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 103-67-3 help many people in the next few years. Category: thiomorpholine.

Toward Rational Design of Amine Solutions for PCC Applications: The Kinetics of the Reaction of CO2(aq) with Cyclic and Secondary Amines in Aqueous Solution

The kinetics of the fast reversible carbamate formation reaction of CO2(aq) with a series of substituted cyclic secondary amines as well as the noncyclic secondary amine diethanolamine (DEA) has been investigated using the stopped-flow spectrophotometric technique at 25.0 degrees C. The kinetics of the slow parallel reversible reaction between HCO3- and amine has also been determined for a number of the amines by H-1 NMR spectroscopy at 25.0 degrees C. The rate of the reversible reactions and the equilibrium constants for the formation of carbamic acid/carbamate from the reactions of CO2 and HCO3- with the amines are reported. In terms of the forward reaction of CO2(aq) with amine, the order with increasing rate constants is as follows: diethanolamine D EA) < morpholine (MORP) similar to thiomorpholine (TMORP) < N-methylpiperazine (N-MPIPZ) < 4-piperidinemethanol (4-PIPDM) similar to piperidine (PIPD) < pyrrolidine (PYR). Both 2-piperidinemethanol (2-PIPDM) and 2-piperidineethanol (2-PIPDE) do not form carbamates. For the carbamate forming amines a Bronsted correlation relating the protonation constant of the amine to the carbamic acid formation rate and equilibrium constants at 25.0 degrees C has been established. The overall suitability of an amine for PCC in terms of kinetics and energy is discussed. Interested yet?

Structure of radical cations of saturated heterocyclic compounds with two heteroatoms as studied by electron paramagnetic resonance, electron – Nuclear double resonance, and density functional theory calculations

The radical cations of piperazine, morpholine, thiomorpholine, and thioxane were investigated by electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) spectroscopy in a solid Freon matrix. Optimized geometry and magnetic parameters of the radical cations were calculated using a density functional theory (DFT)/Perdew-Burke-Ernzerhof (PBE) method. Both experimental and theoretical results suggest that all the studied species adopt chair (or distorted chair) conformations. No evidence for the boat conformers with intramolecular sigma*-bonding between heteroatoms were obtained. In the cases of morpholine and thioxane, the oxygen atoms are characterized by relatively small spin populations, whereas a major part of spin density is located at N and S atoms, respectively. The thiomorpholine radical cation exhibits nearly equal spin population of N and S atoms. In most cases (except for thioxane), the calculated magnetic parameters agree with the experimental data reasonably well.

The design, synthesis and structure-activity relationships associated with C28 amine-based betulinic acid derivatives as inhibitors of HIV-1 maturation

The design and synthesis of a series of C28 amine-based betulinic acid derivatives as HIV-1 maturation inhibitors is described. This series represents a continuation of efforts following on from previous studies of C-3 benzoic acid-substituted betulinic acid derivatives as HIV-1 maturation inhibitors (MIs) that were explored in the context of C-28 amide substituents. Compared to the C-28 amide series, the C-28 amine derivatives exhibited further improvements in HIV-1 inhibitory activity toward polymorphisms in the Gag polyprotein as well as improved activity in the presence of human serum. However, plasma exposure of basic amines following oral administration to rats was generally low, leading to a focus on moderating the basicity of the amine moiety distal from the triterpene core. The thiomorpholine dioxide (TMD) 20 emerged from this study as a compound with the optimal antiviral activity and an acceptable pharmacokinetic profile in the C-28 amine series. Compared to the C-28 amide 3, 20 offers a 2-to 4-fold improvement in potency towards the screening viruses, exhibits low shifts in the EC50 values toward the V370A and Delta V370 viruses in the presence of human serum or human serum albumin, and demonstrates improved potency towards the polymorphic T371A and V362I virus variants.
