A hit optimization procedure based on isosteric and bioisosteric replacement of decorating groups at both the N1 and the C5 phenyl rings of 1,5-diarylpyrroles led to identification of 4-((1-(4-fluorophenyl)-2-methyl- 5-(4-(methylthio) phenyl)-1H-pyrrol-3-yl) methyl) thiomorpholine that is characterized by a very high activity toward both Mycobacterium tuberculosis 103471 and H37Rv strains (MIC values of 0.125 mu g/mL), and a safe profile in terms of cytotoxicity (CC(50) of > 128 mu g/mL) and protection index (> 1000).

Electric Literature of 3068-76-6, New discoveries in chemical research and development in 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 3068-76-6, Name is N-(3-(Trimethoxysilyl)propyl)aniline, SMILES is CO[Si](CCCNC1=CC=CC=C1)(OC)OC, molecular formula is C12H21NO3Si, belongs to thiomorpholine compound. In an article, author is El-Faham, Ayman, introduce new discover of the category.

Here we describe a new family of N-form immonium-type coupling reagents that differ in their carbocation skeleton structure. The N-methylpiperazine derivative failed to form immonium salts, while the thiomorpholine derivative did not give better results than the coupling reagents currently used. The presence of the morpholine had a marked influence on the solubility and stability as well as the reactivity of the reagent. Finally, the fluoroamidinium salt performed extremely well in the presence of only 1 equiv of base, thereby confirming the effect of the proton acceptor in the reaction.

The oxidative anti-Markovnikov amination of styrenes catalyzed by cationic rhodium complexes provides a new access to enamines. As catalyst precursors [Rh(cod)(amine)(2)](+) complexes have been identified and characterized for the first time by X-ray crystallography and NMR. While piperazine, N-methylpiperazine, and thiomorpholine form 1:1 Rh-amine complexes, nonchelating amines such as piperidine and diethylamine form 1:2 Rh-amine complexes. The easier dissociation of the amine ligand explains why monodentate amines give good yields of the corresponding enamines in contrast to bidentate amines. (C) 1998 Elsevier Science S.A.

Application of 1591-31-7, Chemical Research Letters, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 1591-31-7, Name is 4-Iodo-1,1′-biphenyl, SMILES is C2=C(C1=CC=CC=C1)C=CC(=C2)I, belongs to thiomorpholine compound. In a article, author is da Frota, Livia C. R. M., introduce new discover of the category.

The reaction between iodo and N-methyl-piperazine or thiomorpholine in water, in the presence of KI, led to the formation of stable and easy to handle amine-iodine complexes, as the complex morpholine-iodo previously reported in the literature. However, the complex obtained using N,N-tetrametylethylenediamine proved less stable, while no complex was formed when piperidine was used as base. These results show that the presence of a second heteroatom in the structure of amines is of fundamental importance for the formation and stability of these complexes. In this work we describe, for the first time, the use of complexes morpholine-iodo, N-methyl-piperazine-iodo and thiomorpholine-iodo as iodinating reagents of several substituted phenols, leading to iodinated products in good to excellent yields.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research. You can also check out more blogs about 1591-31-7. Application of 1591-31-7.

We have successfully synthesized a new antimony-based halide hydrate, bis(thiomorpholine) pentachloroantimonate(III) monohydrate (C4NSH10)(2)[SbCl5]center dot H2O (1, C4NSH10+ is thiomorpholine cation), which crystals in a centrosymmetric space group of Pbca. 1 features the R2MX5-type perovskite architecture and undergoes a first-order structural phase transition (PT) at 406.3 K, accompanying with prominent dielectric responses. The photoluminescence spectra reveal that 1 shows a broadband light emission and a long lifetime (2.77 mu s). In addition, the DFT calculation exhibits the organic thiomorpholine cation has a contribution to electronic band structures of 1, which is distinct with other halide bismuth (Bi) and antimony (Sb)-based hybrid perovskites. This finding opens up a potential pathway to construct new lead-free hybrid materials for application of the optoelectronics. (C) 2020 Elsevier B.V. All rights reserved.

In a article, author is Kralova, Petra, introduce new discover of the category.

Herein we report the polymer-supported synthesis of 3,4-dihydro-2H-1,4-oxazine-3-carboxylic acid derivatives using immobilized Fmoc-Ser(tBu)-OH and Fmoc-Thr(tBu)-OH as the starting materials. After the solid-phase-synthesis of N-alkyl-N-sulfonyl/acyl intermediates, the target dihydrooxazines were obtained using trifluoroacetic acid-mediated cleavage from the resin. This approach was also studied for the preparation of dihydrothiazines from immobilized Fmoc-Cys(Trt)-OH. Inclusion of triethylsilane in the cleavage cocktail resulted in the stereoselective formation of the corresponding morpholine/thiomorpholine-3-carboxylic acids. Stereochemical studies revealed the specific configuration of the newly formed stereocenter and also the formation of stable N-acylmorpholine rotamers.

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 2471-70-7, you can contact me at any time and look forward to more communication.

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.

Azomethine ylides are accessed under mild conditions via benzoic acid catalyzed condensations of 1,2,3,4-tetrahydroisoquinolines or tryptolines with aldehydes bearing a pendent dipolarophile. These intermediates undergo intramolecular [3 + 2]-cycloadditions in a highly diastereoselective fashion to form polycyclic amines with four new stereogenic centers. Challenging substrates such as piperidine, morpholine, and thiomorpholine undergo the corresponding reactions at elevated temperatures.
