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
Yang, Xiaojuan,Wu, Liqiang
, p. 1327 - 1333 (2013/10/08)
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
Practical and efficient synthesis of 3-aryl-2H-benzo[1,4]thiazine derivatives catalyzed by KHSO4
Baghernejad, Bita,Heravi, Majid M.,Oskooie, Hossein A.
experimental part, p. 589 - 593 (2011/04/15)
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.
Conversion of bis(o-nitrophenyl)disulfides to heterocycles containing sulfur and nitrogen by the action of samarium diiodide
Zhong, Weihui,Chen, Xiaoyuan,Zhang, Yongmin
, p. 156 - 160 (2007/10/03)
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
