This invention relates to novel alkyl pyrrolo (2,3-d) carbazole-6-carboxylates and to addition salts thereof; and to preparation of the same by a synthesis sequence starting from a tryptamine and a 3-halopyruvate and involving a rearrangement of an addition compound with an aldehyde, said rearrangement being effected by Nb-alkylation of the aforementioned addition compound; and to pharmaceutical compositions containing the same; and to novel tetrahy- droazepinoindoles used in the preparation of the same.
Methyleneindolines, indolenines, and indoleniniums. 19. A new entry into the hexahydropyrrolidino[2,3-d]carbazole system
