One-pot synthesis of highly functionalized benzo [1,3] thiazine from isocyanides, aniline, and heterocumulene via Cu-catalyzed intramolecular C-H activation reactions

A one-pot synthesis of functionalized benzo thiazine derivatives via a Cu-catalyzed, multicomponent reaction of isocyanides, aniline, and heterocumulenes in acetonitrile at room temperature was developed. Transition metal-catalyzed activation of C-H bonds under mild copper-catalytic reaction conditions, using simple and available starting materials, also obtaining a pure product with high yield without applying column chromatography are the major advantages of the applied method among the other ones used for this purpose. The structures are confirmed spectroscopically (H-1- and C-13-NMR, IR, and EI-MS) and through elemental analyses.

Radical cation and dication of a 4H-dithieno[2,3-b:3′,2′-e][1,4]-thiazine

A p-tert-butylphenyl substituted 4H-dithieno[2,3-b: 3′,2′-e][1,4] thiazine was synthesized by twofold Buchwald-Hartwig coupling. The electronic properties (UV/Vis, cyclic voltammetry and spectroelectrochemistry) and the DFT-and TD DFT-calculated electronic structure reveal that the parent system and the radical cation and dication oxidation products are highly polarizable p-systems with strong charge transfer contributions. The radical cation and the dication were prepared by oxidation with antimony(V) pentachloride, giving stable deeply colored salts. EPR spectroscopy of the radical cation furnishes hyperfine coupling constants with the nitrogen nucleus and the alpha-thienyl protons. The dication is EPR silent and was structurally characterized by recording an NMR spectrum.

Photodynamic activity of nanostructured fabrics grafted with xanthene and thiazine dyes against opportunistic fungi

Fungi are an important class of human pathogens for which considerable research has gone into defeating them. The photodynamic effects of rose bengal (RB), phloxine B (PB), azure A (AA), and toluidine blue O (TBO) dyes to inhibit Aspergillus fumigatus, Aspergillus niger, Trichoderma viride, Penicillium funiculosum, and Chaetomium globosum were investigated grafted to nano- and micro-structured fabrics. Three antifungal tests conducted: broth microdilution test of free dyes, zone of inhibition and quantitative antifungal assays on fabrics grafted with dyes. In the broth microdilution test, free RB displayed the lowest MIC at 32 mu M to inhibit visible hyphal growth and germination but the antifungal ability of MIC for other photosensitizers below 63 mu M was insignificant. RB and PB showed lower MIC than AA and TBO. In the inhibition zone tests, nanostructured fabrics grafted with RB and PB did not display fungal growth on the surface. Most microstructured fabrics grafted with AA and TBO showed little inhibition. In quantitative antifungal assay, nanostructured fabrics grafted with RB has the largest inhibition rate on T. viride and the lowest inhibition rate on P. funiculosum and the results showed the increasing inhibition rate in the order of AA < TBO < PB < RB.

Ring-contraction from benzo[b][1,4]thiazines to benzo[d]thiazolines induced by oxygen

An unexpected ring-contraction from benzo[b]pyrazino[1,2-d][1,4]thiazine-1,4-diones (6) to benzo[4,5] thiazolo[3,2-a]pyrazine-1,4-diones (7) has been developed. The preliminary mechanistic studies showed the transformation contained two independent steps: the first step is the formation of a Michael adduct upon the addition of the protic solvent, in the presence of base, to the C-2-C-3 double bond of compound 6, and the second step is a ring-contraction induced by oxygen via the migration of sulfur atom from C-2 to C-3 position. And its scope is also studied. (C) 2016 Elsevier Ltd. All rights reserved.

Stereoselective Synthesis and Cytoselective Toxicity of Monoterpene-Fused 2-Imino-1,3-thiazines

Starting from pinane-, apopinane- and carane-based 1,3-amino alcohols obtained from monoterpene-based beta-amino acids, a library of monoterpene-fused 2-imino-1,3-thiazines as main products and 2-thioxo-1,3-oxazines as side-products were prepared via two-or three-step syntheses. When thiourea adducts prepared from 1,3-amino alcohols and aryl isothiocyanates were reacted with CDI under mild conditions, O-imidazolylcarbonyl intermediates were isolated which could be transformed to the desired 1,3-thiazines under microwave conditions. 1,3-Thiazines and 2-thioxo-1,3-oxazine side-products could also be prepared in one-step reactions through the application of CDI and microwave irradiation. The ring-closure process was extended to cycloalkane-based gamma-hydroxythioureas. The carane-and apopinane-based derivatives exhibited marked antiproliferative activity against a panel of human adherent cancer cell lines (HeLa, A2780, MCF7 and A431).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5326-23-8, in my other articles.

Crystal structure of (1S, 2S, 5R)-5-acetylamino-4oxo-2,3-diphenyl-1,3-thiazinan-1-ium-1-olate

The asymmetric unit of the enantiomerically pure title compound, C18H18N2O3S, comprises two independent molecules (A and B) having almost identical conformations. When overlayed, the alignment-r. m. s. deviation value is 0.30 angstrom. The six-membered heterocycle has a twisted half-chair conformation in both molecules. The O atom on the S atom of the ring is pseudo-axial on the thiazine ring and trans to both a phenyl group substituent and the acetamide group in each case. The two benzene rings in each molecule are almost orthogonal to each other, with interplanar dihedral angles of 83.79 (17) and 86.95 (16)degrees. The acetamide group is pseudo-equatorial and a phenyl ring is pseudo-axial on the thiazine ring. Both molecules show a weak intramolecular C-H center dot center dot center dot O interaction between H-atom donors of one of the phenyl rings and the acetamide group. In the crystal, an intermolecular N-H center dot center dot center dot O( thiazine) hydrogen bond links B molecules along the 21 (b) screw axis and, in addition, an N-H center dot center dot center dot O( acetamide) hydrogen bond links A and B molecules across a. A two-dimensional layered structure lying parallel to (001) is generated, also involving weak intermolecular C-H center dot center dot center dot O interactions.

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 26978-64-3. COA of Formula: C4H10O4S.

Direct hydroxyethylation of amines by carbohydrates: Via ruthenium catalysis

An efficient and halogen-free catalytic methodology for the synthesis of beta-amino alcohols from aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogen borrowing for the reduction of the imine intermediate. A series of arylamines bearing various substituents were successfully transformed into the desired products in good to excellent yields.

A review on synthesis of benzothiazine analogues

Scientific advances mainly involves the development of new and highly reactive compounds. Nitrogen and sulphur containing benzothiazines forms highly active heterocyclic agents. Benzothiazines are prominent class of heterocyclic compound. Many studies have been done in the development of benzothiazine analogues. Microwave assisted synthesis, regioselective techniques and other methods are also used for benzothiazine synthesis. Various methods have been developed for the synthesis of benzothiazine derivatives. Benzothiazines exhibits numerous therapeutic activities like anti-HIV, calcium antagonistic, anti-serotinin, analgesic, anti-mycobacterial anti-microbial, anti-oxidant, anti-rheumatic, anti-inflammatory, anti-hypertensive ,calcium channel blocker, anti-malarial, potassium channel opener, cardiovascular, anthelmintic, neuroprotective, aldose reductase inhibitor, herbicidal, pesticidal etc. This has raised the necessity to explore novel benzothiazine derivatives which can significantly contribute to the development of therapeutically active agents. And the newer development of novel benzothiazines derivatives also involves the same characteristic features and also contribute various activities.
