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. Quality Control of (E)-1-Methoxy-4-(prop-1-en-1-yl)benzene, The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic.

Synthesis and biological evaluation of heteroalicyclic cyanoguanidines at histamine receptors

Recent studies on histamine receptor (HR) subtypes identified imidazolyl butyl cyanoguanidines, like UR-PI376, as highly potent agonists at the human histamine H-4 receptor (hH(4)R). While imidazole-containing compounds display drawbacks in pharmacokinetics, we studied the possibility of replacing the heteroaromatic cycle by nonaromatic six-membered heterocycles (piperidine, morpholine, thiomorpholine, and N-methylpiperazine) as potential bioisosteres. Beyond that, this approach should give more information about the indispensability of the aromatic ring as a basic head group. Besides these changes, a variation of the spacer length (C-3-C-5) connecting the heterocycle and the cyanoguanidine moiety has been made to possibly trigger the selectivity towards the respective HRs. Investigations in radioligand-binding assays exhibited only very weak activity at the hH(1)R and hH(3)R, while nearly all compounds were inactive at the hH(2)R and hH(4)R. In the case of piperidine-containing compounds, moderate affinities at the hH(3)R over the single-digit micromolar range were detected.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Welcome to check out more blogs about 489-84-9, in my other articles. SDS of cas: 489-84-9.

Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: A test of N-glycosylation methodologies on a lipophilic peroxide

10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-beta-bromide that with amine nucleophiles provided the amino-artemisinins. In an attempt to develop more economic approaches, direct N-glycosylation of DHA was examined but 2-deoxyartemisinin was invariably obtained. However, hydroxyl group activation by conversion into the 10 beta-halide in non-polar solvents with anhydrous HCl and Group I and II metal halides, oxalyl chloride or thionyl chloride with catalytic DMSO, and oxalyl bromide did succeed. The beta-halides were converted in situ by thiomorpholine into artemiside, and by thiomorpholine-1,1-dioxide into artemisone respectively in scalable reactions. Hydrogen peroxide-acetonitrile or the urea-hydrogen peroxide complex efficiently oxidized the sulfide artemiside to the sulfone artemisone. Overall, a generalized approach to 10-alkylamino-artemisinins is now available. (C) 2018 Elsevier Ltd. All rights reserved.

New optimized piperamide analogues with potent in vivo hypotensive properties

We describe herein the structural optimization of new piperamide analogues, designed from two natural prototypes, piperine 1 and piper-dardine 2, obtained from Piper tuberculatum Jacq. (Piperaceae). Molecular modeling studies using semiempirical AMI method were made in order to establish rational modifications to optimize them by molecular simplification. The targeted compounds (10) and (11) were respectively obtained using benzaldehyde (12) and para-anisaldehyde (13) as starting materials. H-1 NMR spectra showed that the target compounds were diastereoselectively obtained as the (E)-isomer, the same geometry of the natural prototypes. These new synthetic amides presented significant hypotensive effects in cardiovascular essays using in vivo methodologies. Compound 11 (N-[5-(4′-methoxyphenyl)2(E)-pentenoyl]thiomorpholine) showed a potency 10,000 times greater than its prototype 5, evidencing an optimization of the molecular architecture for this class of hypotensive drug candidates.

Degradation of morpholine and thiomorpholine by an environmental Mycobacterium involves a cytochrome P450. Direct evidence of intermediates by in situ H-1 NMR

A strain of Mycobacterium sp. RP1 was isolated from a contaminated activated sludge. It was capable of utilizing morpholine, a waste of chemical industry, as sole source of carbon, nitrogen and energy. The kinetic of biodegradation of morpholine was followed directly on the incubation medium using in situ H-1 NMR. This technic allowed to identify two intermediates of the degradative pathway: glycolate and 2-(2-aminoethoxy)acetate. The inhibitory effects of metyrapone on the degradative abilities of the strain RP1 indicated the involvement of a cytochrome P450. This observation was confirmed by spectrophotometric analysis and H-1 NMR. Metyrapol, a known metabolite of metyrapone, was also found to be an inhibitor. The same study of degradation of thiomorpholine showed the formation of sulfoxide, which confirmed the presence of a cytochrome P450. (C) 1998 Elsevier Science B.V. All rights reserved.

Energetics and Reactivity of Morpholine and Thiomorpholine: A Joint Experimental and Computational Study

The influence of the heteroatoms in the conformational, energetic, and reactivity trends exhibited by morpholine and thiomorpholine isosteres was obtained from computational and experimental thermochemical studies. For those purposes, the gas-phase standard (p = 0.1 MPa) molar enthalpies of formation of the compounds, at T = 298.15 K, were determined from the experimental values of the standard molar. enthalpies of formation, in the liquid phase, and of the standard molar: enthalpies of vaporization, obtained by calorimetric techniques, and also from composite G3(MP2)// B3LYP calculations making use of appropriate working reactions. A very good agreement was found between the calculated and the experimental gas-phase enthalpies of formation. The computational study was further extended to the calculation of other gas-phase thermodynamic properties these compounds, namely, the N-H or C-H bond dissociation enthalpies, gas-phase acidities and basicitics, proton affinities and adiabatic ionization enthalpies, and the energies and structures of the conformational stereoisomers of morpholine and thiomorpholine.

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. Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 1074-36-8, you can contact me at any time and look forward to more communication.
