Description:
Three new C 19 -diterpenoid alkaloids, named aconitramines A ( 1 ), B ( 2 ), and C ( 3 ), were isolated from Aconitum transsectum. By UV, IR, 1D- and 2D-NMR, and MS analyses, their structures were elucidated as 18-methoxyvilmoraconitine, 18-demethoxydolichotine A, and 18-demethoxydolichotine B. Compound 1 is the second known C 19 -diterpenoid alkaloid with a three-membered ring formed by C(8), C(9), and C(10).
