BiOCl Pro-Catalyzed Synthesis of Benzoxazepines from 4'-Hydroxy-3', 5'- Dinitro Substituted Chalcones and Ortho-Aminophenol
K. L. Ameta.
The present study describes the Bi (III) chloride catalyzed transformation of 4'-hydroxy-3',5'-dinitrochalcones
into the corresponding benzoxazepines followed by sequential Michael addition using Bi (III) oxychloride as a procatalyst
Keywords: Benzoxazepines, pro-catalyst, chalcones, Michael addition.
