A series of novel piperidine, piperazine, morpholine and thiomorpholine appended dibenzo[b,d] thiophene-1,2,3-triazoles were designed and synthesized utilizing azide-alkyne click chemistry in the penultimate step. The required azide building block 6a-e was synthesized from commercial dibenzo[b, d] thiophene in good yields following five step reaction sequence. All the new analogues 8a-f, 9a-f, 10a-f, 11a-f & 12a-f were characterized by their NMR and mass spectral analysis. Screening all thirty new compounds for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv, resulted 8a, 8f and 11e as potent analogues with MIC 0.78 mu g/mL, 0.78 mu g/mL & 1.56 mu g/mL, respectively, and has shown lower cytotoxicity. Interestingly, all six piperazine appended dibenzo[b, d] thiophene-1,2,3-triazoles 11a-f exhibited Mtb inhibition activity with MIC 1.56-12.5 mu g/mL. To some extent, the data observed here indicated Mycobacterium tuberculosis inhibition among the appendages is in the order, piperazine > thiomorpholine > morpholine. (C) 2016 Elsevier Ltd.

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards., Formula: https://www.ambeed.com/products/177034-57-0.html, 177034-57-0, Name is 4-((2-Isopropoxyethoxy)methyl)phenol, molecular formula is C12H18O3, belongs to thiomorpholine compound. In a document, author is Shi, TS, introduce the new discover.

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).

The molecular structures of [ZnLCl2], [PdL](ClO4)(2) and [RhLCl2]PF6 were determined by X-ray diffraction. In [ZnLCl2], the ligand acts in a bidentate fashion using its two N atoms while the two S atoms remain free and the coordination structure is a distorted tetrahedron. [PdL](ClO4)(2) possesses a distorted square planar coordination geometry with all the four hetero atoms being coordinated. The coordination structure of [RhLCl2]PF6 is a distorted octahedron with the two Cl atoms in trans position and L also acting as a tetradentate ligand. In addition to the crystal structures, the dynamic H-1 NMR behaviour of the three complexes were also investigated. (C) 1999 Elsevier Science S.A. All rights reserved.

In a document, author is Hanif, KM, introduce the new discover.

The reaction of thiomorpholine (C4H9NS) with [Ru-3(CO)(12)] at 68 degrees C afforded [Ru-3(mu-H)(mu-eta(2)-SCH2CH2NH2)(CO)(9)] 5 in 25% yield. An X-ray structure determination of 5 showed that it consists of a closed triruthenium cluster with a mu-eta(2)-SCH2CH2NH2 ligand formed by the ring-opening cleavage of thiomorpholine with elimination of a C-2 fragment. In contrast the analogous reaction of thiazolidine (C3H7NS) with [Ru-3(CO)(12)] yielded the dinuclear compound [Ru-2(mu-eta(3)-SCH2CH2NHCH3)(CO)(6)] 6 (28%), which was found to contain a mu-eta(3)-SCH2CH2NHCH2 ligand formed by the ring-opening cleavage of the C-S bond of the thiazolide ligand.

Secondary amines react with thiosalicylaldehydes in the presence of catalytic amounts of acetic acid to generate ring-fused N,S-acetals in redox-neutral fashion. A broad range of amines undergo alpha-sulfenylation, including challenging substrates such morpholine, thiomorpholine, and piperazines. Computational studies employing density functional theory indicate that acetic acid reduces the energy barriers of two separate steps, both of which involve proton transfer.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.you can check my other blog about 653-37-2, you can contact me at any time and look forward to more communication.

In a document, author is Lim, MH, introduce the new discover.

The ruthenium(II) porphyrin fluorophore complexes [Ru(TPP)(CO)(Ds-R)] (TPP = tetraphenylporphinato dianion; Ds = dansyl; R = imidazole (im), 1, or thiomorpholine ™, 2) were synthesized and investigated for their ability to detect nitric oxide (NO) based on fluorescence. The X-ray crystal structures of 1 and 2 were determined. The Ds-im or Ds-tm ligand coordinates to an axial site of the ruthenium(II) center through a nitrogen or sulfur atom, respectively. Both exhibit quenched fluorescence when excited at 368 or 345 nm. Displacement of the metal-coordinated fluorophore by NO restores fluorescence within minutes. These observations demonstrate fluorescence-based NO detection using ruthenium porphyrin fluorophore conjugates.
