Abstract

Two known, but previously uncharacterized, ent-kaurenic acid derivatives, 1 and 2, and four new sesquiterpenes of the eudesmanolide type, 3–6, have been isolated from Wedelia prostata. The structures were eludidated by a range of ID and 2D high field nmr techniques, and the stereochemistry of the new eudesmanolides was defined from a combination of coupling constant analyses and nuclear Overhauser difference spectra. © 1993, American Chemical Society.
