Abstract
Benzodiazepines 3a–d have been synthesized by the reaction of exocyclic α,β-unsaturated ketones 1a–d with 1,2-phenylenediamine in hot ethanol. Acetylation of compounds 3a–d with a mixture of acetic anhydride and anhydrous pyridine affords the N-acetyl derivatives 4a–d. Structure and stereochemistry of the synthesized compounds have been elucidated by various NMR techniques.
