Imino-bridged Heterocycles. II (1). Regiospecific Synthesis of the 11H-Benzocycloheptapyridin-6,11-imine and 5H-Benzocycloheptapyridin-5,10-imine Systems

Regiospecific synthetic pathways for two of the eight isomeric benzocycloheptapyridinimines have been developed based upon intramolecular acid catalyzed additions between an amine function and an internal olefin.The requisite amines were generated from known tricyclic ketones by ketimine formation followed by sodium borohydride reduction.
