Abstract

The complete assignments of four lycopodium triterpenoids, lycoclavanol, lycoclaninol, 21-epi-serratenediol and serratenediol, were accomplished by the use of a new two-dimensional technique, HMBC (heteronuclear multiple bond connectivity). It appears this technique is extremely powerful for the structural analysis of complicated compounds with many methyl groups.
