Construction of an Octahydropyrido[3,4-b]carbazole Skeleton

The octahydropyridocarbazole skeleton is an important key structure for the synthesis of pyridocarbazole alkaloids, including the antineoplastic agent ellipticine and related compounds. In the present work, an octahydropyrido[3,4-b]carbazole derivative and a number of new tetrahydrocarbazole derivatives were synthesized utilizing a new synthetic pathway
