Condensation of 5-amino, 6-amino, 7-amino and 8-amino-2,2-dimethyl-2H-chromenes with either 6-bromoveratraldehyde or 6-chloropiperonal afforded the corresponding Schiff bases, which were subsequently reduced to the corresponding benzylchromenylamines 30-33 and 36-39. Lithium diisopropylamide-mediated cyclization of those amines, followed by spontaneous air oxidation, afforded
