Reactions of 5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazole and of 5,6,9,10,11,12-hexahydro-4H,8H-cyclohepta[4,5]pyrrolo[3,2,1-ij]quinoline with arenesulphonyl azides

Abstract

The title hexahydropyridocarbazole reacts with arenesulphonyl azides giving either cis- or trans-11a-arylsulphonylamino-8-arylsulphonylimino-octahydrocyclopenta[4,5]pyrido[3,2,1-ij]quinoline [(4) or (6)], depending on the solvent. The hexahydrocycloheptapyrroloquinoline yields either a phenanthridine (13) or a 2,4-butanoquinoline (16) under the same conditions.
