摘要
One new lycopodine-type Lycopodium alkaloid, dehydroisofawcettiine N-oxide (1) and eleven known analogues (2-12) were isolated from the whole plant of Diphasiastrum complanatum. The new structure was established on the basis of spectroscopic methods, including 2D NMR techniques. The absolute configurations of 2 and its new N-oxide derivative (1) were deduced by chemical transformation combined with Cotton effects in their electronic circular dichroism (ECD) spectra.
