Fungal metabolites. Part 15. Structure and chemical correlations of uvidin C, D, and E, new drimane sesquiterpenes from Lactarius uvidus Fries
Abstract
Uvidin C (3), uvidin D (6), and uvidin E (10) have been isolated from Lactarius uvidus Fries (Basidiomycetes). The structures, including the absolute stereochemistry, of these three uvidins have been determined by spectroscopic data and chemical correlations with the known (+)-uvidin A (1).
