L. Garlaschelli et al., FUNGAL METABOLITES .32. NEW FATTY-ACID ESTERS OF DRIMANE SESQUITERPENES FROM LACTARIUS-UVIDUS, Journal of natural products, 57(7), 1994, pp. 905-910
This study of lipids of Lactarius uvidus has revealed the presence of
new fatty acid esters of uvidin A [2a-d] and drimenol [6a-d]. Treatmen
t of uvidin A [1] with base induced a Favorskii-like rearrangement lea
ding to compounds a with a new sesquiterpenoid skeleton. Uvidin A [1]
showed insect antifeedant and cytotoxic activities.
