Efficient one pot synthesis of [1,2,4]triazolo[4,3- α ][1,4] benzodiazepines derivatives
ABSTRACT Efficient one pot synthesis of [1,2,4]triazolo[4,3- α ][1,4]benzodiazepines derivatives.chloro-6-phenyl-1-(substituted)-4H-[1,2,4]triazolo[4,3 α ][1,4]benzodiazepine were efficiently synthesized by oxidative cyclization reaction of 2-hydrazino-1,4-benzodiazepines with various aldehydes in presence of diacetoxy iodobenzene.
