Kopsiyunnanines J1 and J2, new strychnos-type homo-monoterpenoid indole alkaloids from Kopsia arborea.
Two new indole alkaloids, kopsiyunnanines J1 and J2, were isolated from Yunnan Kopsia arborea, and their structures were determined by spectroscopic analyses. Kopsiyunnanines J1 and J2 are unprecedented Strychnos-type indole alkaloids having an additional C1 unit in the secologanin moiety of the molecule.
