The alkaloids of Ophiorrhiza cf. ferruginea

Extraction of the aerial parts of Ophiorrhiza cf. ferruginea (Rubiaceae) has yielded the tertiary indole alkaloids dihydrocycloakagerine (1), 3, 14-dihydrodecussine (mostuenine) (3) and tetrahydroakagerine (4), and the quaternary indole alkaloid isomalindine (5). The structures of dihydrocycloakager...

Description
Summary:Extraction of the aerial parts of Ophiorrhiza cf. ferruginea (Rubiaceae) has yielded the tertiary indole alkaloids dihydrocycloakagerine (1), 3, 14-dihydrodecussine (mostuenine) (3) and tetrahydroakagerine (4), and the quaternary indole alkaloid isomalindine (5). The structures of dihydrocycloakagerine (1) and isomalindine (5) are confirmed by the X-ray method.
