Base-induced reactions of N-methyl quaternary salts of 11b-methyl-7,11b-dihydro-5H-isoindoloisoindole (4), which were effectively transformed from readily available 1-azadibenzobicyclonona-3,6-dienes (1), were examined and consequently, 5,12-dimethyl-5,10-imino-10,11-dihydro-5H-dibenzocycloheptens (6) and 6,10b-dimethyl-5,6,6a,10b-tetrahydrobenzocyclobutisoquinolines (7) were obtained via Stevens rearrangement.
