An efficient, environmentally benign, and solvent-free protocol for the synthesis of 4-substituted 1,5-benzodiazepines catalyzed by reusable sulfated polyborate
An efficient and environmentally benign method has been developed for the one-pot solvent-free synthesis of 4-substituted-1,5-benzodiazepines via three-component reaction of o-phenylenediamine, dimedone with a variety of aldehydes catalyzed by sulfated po

NOVEL SYNTHESES OF HETEROCYCLES WITH N-(1-HALOALKYL)AZINIUM HALIDES: PART 6. PREPARATION OF 2,3,4,5,10,11-HEXAHYDRO-1H-DIBENZODIAZEPIN-1-ONES
Conversion of aldehydes into N-(1-chloroalkyl)pyridinium chlorides (by means of pyridine and thionyl chloride) and further reaction with 3-(2-aminophenyl)amino-5,5-dimethyl-2-cyclohexenone provide a novel and efficient route to the title compounds.
