A facile two-step synthetic route for preparing the novel tetracyclic skeleton of benzofused 2,6-diaryl-1-azahomoisotwistanes 2 had been developed. The route was carried out by a one-pot tandem cross-coupling reaction of o-allylbenzaldehydes 1 with aryl methylketones 3, and NH4OAc mediated the cascade cyclocondensation reaction of the resulting 1,5-diketones 4 with the 3-o-allylphenyl group in good
