The structures of new diterpene alkaloids, ezochasmanine, ezochasmaconitine, and anisoezochasmaconitine, have been established as 3-hydroxychasmanine, 14-acetyl-8-benzoylchasmanine, and 14-acetyl-8-anisoylchasmanine respectively, in correlation with a known alkaloid chasmanine.Vilmorrianine A (8-acetyl-14-anisoylezochasmanine) was synthesized from ezochasmanine via benzoylation, trichloroethoxycarbonylation, acetylation and elimination reaction of trichloroethoxycarbonyl group.
