methodology has been realized for the synthesis of 7-substituted 2,3,4,5-tetrahydro-1-benzazepine derivatives with Suzuki-Miyauracross-coupling, aza-Claisen rearrangement and ring-closingmetathesis (RCM) the key steps. Here, o-allylacetanilide derivatives were obtained by Suzuki-Miyauracross-coupling of the corresponding o-iodoacetanilides. The o-allylacetanilides, on N-allylation under phase-transfter catalysis
