Hydrogen-bond basicity pK(HB) scale of secondary amines

Using 4-fluorophenol as a reference hydrogen-bond donor, equilibrium constants K for the formation of 1 : 1 hydrogen-bonded complexes have been obtained by FTIR spectrometry for 33 secondary amines in CCl4 and/or C2Cl4 at 298 K. A spectroscopic scale of hydrogen-bond basicity is constructed from the IR frequency shift Av(OH) of methanol hydrogen-bonded to secondary amines. The comparison of the pK(HB) (log K), Deltav(OH), and pK(a) scales points to the sensitivity of pK(HB) to steric effects, and of Deltav(OH) to the p character of the nitrogen lone pair. The pKHB scale of secondary amines extends from 2.59 for pyrrolidine to -0.45 for (Me3Si)(2)NH. The main effects explaining the pK(HB) variations are (i) the opposite polarizability and steric effects in alkylamines, (ii) field-inductive effects (e.g N drop CCH2NHMe), (iii) intramolecular hydrogen bonding, e.g. in (MeOCH2CH2)(2)NH, and (iv) the ring size giving the order: pyrrolidine = azetidine > piperidine > 2-methylaziridine > azepane. IR spectra show the attachment of 4-fluorophenol to the nitrile nitrogen of N drop CCH2NHMe and N drop CCH2CH2NHMe, to the oxygen of morpholine and (MeOCH2CH2)(2)NH, and to the sulfur of thiomorpholine and thiazolidine, in addition to attachment to the amino nitrogen. The correlation of pK(HB) with the minimum electrostatic potential on the nitrogen lone pair is used for unravelling the basicity of each nitrogen of 1-methyl-1,4-diazepane.

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.

Structure-reactivity correlations for complex formation reactions between square-planar metal centers and thioethers

Kinetics for complex formation between Pd(H2O)(4)(2+) and thioethers of largely varying electronic and steric properties, viz. MeSCH(2)COOH, (n-Pr)(2)S, EtSCH(2)CH(2)OH, S(CH2CH2CH2OH)(2), S(CH2CH2OH)(2), EtSCH(2)COOH, S(CH2COOH)(2), S(CH2CH2COOH)(2), (i-Pr)(2)S, (s-Bu)(2)S, (t-Bu)(2)S, and protonated thiomorpholine, S(C2H4)(2)NH2+, has been studied by use of stopped-flow spectrophotometry in an acidic aqueous medium. Second-order rate constants k(1)(298) are 1.61 x 10(4), 8.0 x 10(4), 3.79 x 10(4), 3.69 x 10(4), 2.21 x 10(4), 1.84 x 10(4), 1.91 x 10(3), 1.34 x 10(4), 1.52 x 10(4), 7.75 x 10(3), 900, and 5.2 x 10(3) M(-1) s(-1), respectively. The reactivity toward Pd(H2O)(4)(2+) of all thioethers studied so far can be described as a function of their sigma-donor properties as expressed by the sum of the Taft constants, Sigma sigma*, and their steric requirements as defined by cone angles, theta, by use of the equation: log k(1) = (9.9 +/- 0.3) – (0.67 +/- 0.05)Sigma sigma* – (0.059 +/- 0.003)theta. Similarly, second-order rate constants k(298) reported previously for reactions between thioethers and Pd(dien)H2O2+ and Pt(dienBr+ are described by log k(298) = (10.5 +/- 0.6) – 0.67 Sigma sigma* – (0.081 +/- 0.006)theta and log k(298) = (4.6 +/- 0.6) – 0.72 Sigma sigma* – (0.080 +/- 0.006)theta, respectively. Hence, the reactivity trends of thioethers toward square-planar complexes can be given a general interpretation in terms of intrinsic, electronic, and steric parameters, by use of log k = gamma + alpha Sigma sigma* + beta theta. Large variations in both electronic and steric properties of the entering ligands indicate that there is no ”duality behavior” in the reactions of thioethers with square-planar metal centers, as claimed in previous literature. No steric threshold is observed for these sterically unhindered systems. There is a rough compensation effect between Delta H-1 double dagger and Delta S-1 double dagger, i.e. a smaller Delta H-1 double dagger is usually accompanied by a larger negative Delta S-1 double dagger, indicating that all thioethers react via the same mechanism. It appears that the much lower reactivity observed for the highly branched (t-Bu)(2)S is primarily caused by a high activation enthalpy. Volumes of activation have been determined for a series of thioethers with a constant cone angle, viz. EtSCH(2)COOH, S(CH2COOH)(2), and S(CH2CH2COOH)(2) through high-pressure stopped-flow measurements. Values of Delta V-1 double dagger are -7.9 +/- 0.5, -8.1 +/- 0.4, and -7.6 +/- 0.3 cm(3) mol(-1), respectively. These values together with that for Et(2)S (-8.7 +/- 0.1 cm(3) mol(-1)) determined previously shows that variation of electronic properties, steric factors being kept constant, change the reactivity markedly, but have no observable influence on the activation volumes. Stability constants beta(1) for five palladium thioether complexes derived as the ratio between rate constants for forward and reverse reactions vary between (1.2 +/- 0.3) x 10(4) and (3.2 +/- 0. 7) x 10(4) M(-1).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 589-87-7. Category: thiomorpholine.

The application of a chiral ligand-exchange column (CLEC) for the direct high-performance liquid chromatographic enantioseparation of unusual secondary amino acids using D-penicillamine-Cu(II) complex as chiral selector is reported. The amino acids investigated were pyrrolidine-2-carboxylic acid, piperidine-2-carboxylic acid, piperazine-2-carboxylic acid, morpholine-3-carboxylic acid, and thiomorpholine-3-carboxylic acid analogs. Chromatographic results are given as the retention, separation, and resolution factors. The chromatographic conditions were varied to achieve optimal separation. The elution sequence of the enantiomers was determined and in most cases the S isomer eluted before R.

Design, synthesis and primary activity of thiomorpholine derivatives as DPP-IV inhibitors

Thirteen thiomorpholine-bearing compounds were designed and synthesized as dipeptidyl peptidase IV (DPP-IV) inhibitors, with natural and non-natural L-amino acids as the starting materials. Their structures were characterized by H-1 NMR, C-13 NMR and HR-MS. The target compounds were screened for the DPP-IV inhibition, and the preliminary SAR result was obtained. Particularly, compounds 4c, 4d and 4f with good DPP-IV inhibition in vitro were further evaluated through a mouse oral glucose tolerance test (OGTT). The preliminary result showed the potential value for further studies on those thiomorpholine-bearing compounds as DPP-IV inhibitors. (C) 2011 Hai Hong Huang.

Synthesis, spectroscopic characterization, DFT studies, and preliminary antimicrobial evaluation of new antimony(III) and bismuth(III) complexes derived from 1,3,5-triazine

Herein, we describe the synthesis and characterizations of 2,4,6-tris(thiomorpholine)-1,3,5-triazine, 2,4,6-tris(piperazine)-1,3,5-triazine and their new Sb(III) and Bi(III) complexes. Characterizations of the ligands and complexes were carried out by elemental analysis, thermogravimetric analysis (TGA), and spectroscopic methods such as infrared (IR), H-1 and C-13 nuclear magnetic resonance (NMR), and single crystal X-ray. Theoretical vibrational frequencies and H-1 and C-13 NMR chemical shifts of free ligands as well as their Sb(III) and Bi(III) complexes have been calculated using density functional theory (DFT/B3LYP and M06-2X) methods. Our theoretical results matched the corresponding experimental data and helped with the interpretation of the IR and H-1 and C-13 NMR spectra. The antimicrobial in vitro studies were carried out against bacterial species Staphylococcus aureus and fungal species Candida albicans, Candida tropicalis, and Candida krusei by the microdilution method. The preliminary antimicrobial evaluations indicated that Sb(III) complexes showed moderate activities against all tested strains of bacterial and fungal with minimum inhibitory concentration (MIC) in range of 512-1024 mu g mL(-1).
