Bioglycerol-based sulfonic acid-functionalized carbon catalyst as an efficient and reusable catalyst for one-pot synthesis of 3- substituted-2 h -1,4-benzothiazines

A simple and efficient synthetic protocol has been developed for the synthesis of 3-substituted-2H-1,4-benzothiazines by using bioglycerol-based sulfonic acid-functionalized carbon catalyst, devoid of corrosive acidic and basic reagents. The developed met

[Ir(P-OP)]-catalyzed asymmetric hydrogenation of diversely substituted C=N-containing heterocycles

Iridium(I) complexes of enantiomerically pure phosphine-phosphite ligands ([Ir(Cl)(cod)(P - OP)]) efficiently catalyze the enantioselective hydrogenation of diverse C=N-containing heterocyclic compounds (benzoxazines, benzoxazinones, benzothiazinones, and quinoxalinones; 25 examples, up to 99% ee). A substrate-to-catalyst ratio as high as 2000:1 was reached.

Practical and efficient synthesis of 3-aryl-2H-benzo[1,4]thiazine derivatives catalyzed by KHSO4

KHSO4 efficiently catalyzes the condensation of o-aminothiophenols and 2-bromo-1-aryl-ethanones to yield 3-aryl-2H-benzo[1,4] thiazines in good yields.

From phenothiazine to 3-phenyl-1,4-benzothiazine derivatives as inhibitors of the Staphylococcus aureus NorA multidrug efflux pump

Overexpression of efflux pumps is an important mechanism by which bacteria evade effects of substrate antimicrobial agents and inhibition of such pumps is a promising strategy to circumvent this resistance mechanism. NorA is a Staphylococcus aureus multid

Conversion of bis(o-nitrophenyl)disulfides to heterocycles containing sulfur and nitrogen by the action of samarium diiodide

Treatment of bis(o-nitrophenyl)disulfides 1 with SmI2 led to simultaneous reduction of nitro groups and reductive cleavage of S-S bonds as well as the formation of the active intermediates 2. The intermediates 2 reacted smoothly with aldehydes

New dyes based on 3-aryl-benzo- and -naphtho-1,4-thiazines

3-Aryl-2H-1,4-benzothiazines have been converted into cyanine dyes by condensing their hydroperchlorates with aldehydes, and into azo-compounds by coupling with reactive diazonium salts. The azo-compounds were also obtained by condensing arylglyoxal hydra
