The first and biomimetic construction of the new skeleton of gelselegine-type oxindole alkaloids
摘要:
Starting from a sarpagine-type indole alkaloid 8, the first and biomimetic construction of a new skeletal type of Gelsemium alkaloid, N(a)-demethoxy-11-methoxy-19-(R)-hydroxygelselegine (13), was stereoselectively achieved via a biogenetically hypothetical aziridine intermediate 12.
