Sutezolid is a new oxazolidinone derivative currently in clinical trials to determine its safety and efficacy towards highly drug-resistant tuberculosis. The aim of the study was the spectroscopic identification of selected key intermediate products of the chiral pool synthesis of sutezolid: (S1) (4-(2-fluoro-4-nitrophenyl)thiomorpholine), (S2) 4-[2-fluoro-4-(benzyloxycarbonyl)aminophenyl] thiomorpholine, (S4) (R)-[[3-[3-fluoro-4-(4-thiomorpholinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]-p-toluenesulfonate, (S5) (R)-[[3-(3-fluoro-4-(4-thiomorpholinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]azide, as well as (S6) sutezolid, the final synthesis product. Spectroscopic identification was carried out based on infrared spectra analysis (FT-IR) and Raman scattering. This part of the analysis was supported by quantum chemical calculations based on the density functional theory (DFT) utilizing the B3LYP hybrid functional and the 6-31G(d,p) basis set to obtain reference standards for intermediates and sutezolid. Additionally, the sutezolid configuration was confirmed by analysing the electronic circular dichroism (ECD) spectra of (S)-and (R)-isomers, combined with the time-dependent DFT calculations to simulate ECD spectra depending on the solvent and type of conformers.

A naphthalimide-based ratiometric fluorescent probe for determining glutathione (GSH) was constructed by installing two oxidized morpholine (e.g. thiomorpholine-S-dioxide and morpholine-N-oxide) components on the off-to-on GSH probe. This probe displayed high selectivity towards GSH. As well, the bioimaging application confirmed that this probe was capable of acting as an indicator to monitor the intracellular GSH. Thus, this work provides a promising strategy to construct the ratiometric fluorescent probe. (C) 2017 Elsevier Ltd. All rights reserved.

A series of novel oxazolidinone antibiotics having [2.2.1] and [2.2.2] bicyclic oxazine moieties at the C-5 side chain of the A-ring was synthesized by nitroso Diels-Alder reactions, from three linezolid analogs containing morpholine, piperazine and thiomorpholine, respectively, as the C-ring components.

New Advances in Chemical Research, May 2021. The prevalence of solvent effects has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. In an article, author is Cincic, Dominik, once mentioned the application of 611-19-8, Name is 1-Chloro-2-(chloromethyl)benzene, molecular formula is C7H6Cl2, molecular weight is 161.03, MDL number is MFCD00000893, category is thiomorpholine. Now introduce a scientific discovery about this category, Quality Control of 1-Chloro-2-(chloromethyl)benzene.

We demonstrate the supramolecular and structural equivalence of two halogen-bond donors (I and Br) and three acceptors (O, NH and S) through the synthesis of seven isostructural halogen-bonded cocrystals, involving six different molecules: 1,4-dibromo- and 1,4-diiodotetrafluorobenzene (donors) and thiomorpholine, thioxane, morpholine, and piperazine (acceptors). ne formation of isostructural cocrystals indicates how cocrystallization may be used to overcome shape and functional group dissimilarities that control molecular arrangement in the solid state. The differences in composition between the seven isostructural cocrystals directly affect the strength and nature of halogen bonds between their constituents, allowing the systematic variation of cocrystal physical properties, in particular the melting point, without affecting their crystal structure. Replacement of each O or S halogen-bond acceptor with an NH group provided an approximate 70 degrees C increase in melting point, whereas the replacement of I with Br as the halogen-bond donor lowered the melting point of the resulting solid by a similar amount.

I am very proud of our efforts over the past few months and hope to 611-19-8 help many people in the next few years. Quality Control of 1-Chloro-2-(chloromethyl)benzene.

Complexes of 1,3-bis(thiomorpholino)propane (L) with Zn(II), Pd(II), Pt(II) and Rh(III) of the formula [ZnLCl2], [ML](ClO4)(2), (M = Pd and Pt), [RhLCl2]Cl . 4H(2)O and [RhLCl2]PF6 were prepared and characterised. 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.

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.
