Total synthesis of lennoxamine and chilenine via ring-expansion of isoindoloisoquinoline to isoindolobenzazepine

Convenient synthesis of the benzazepine alkaloids, lennoxamine (1) and chilenine (2), is described. The key steps are conversion of methylenelactam (5) to an N-tertiary acyliminium ion precursor (16) and a novel expansion of the six-membered ring of 4 to a benzazepine ring system (3b), which could be transformed into lennoxamine (1) and chilenine (2).
