Cyclic guanidines; V. Synthesis of novel benzodiazepinoid and related systems by intramolecular electrophilic aromatic substitution

A convenient route to pentacyclic benzodiazepines and quinoxalines is reported, which simultaneously represent cyclic guanidines. Five new heterocyclic ring systems are described and the rules governing the regioselectivity of some of the ring closure rea
