The reactions of 1-benzoyl-2,4-diphenyl-2,3-dihydro-1H-1,5-benzodiazepine with methyl 1-bromocycloalkanecarboxylates and zinc, followed by hydrolysis of the reaction mixtures, resulted in the formation of spiro-δ-lactams bearing a 2-(N-benzoylamino)phenyl substituent at the nitrogen atom. The product structures were confirmed by X-ray structural analysis, and a mechanism was proposed for the product formation.
