ABSTRACT
Racemates of the diphenolic metabolites (±)-tylopilusin A (1) and (±)-tylopilusin B (2) were isolated from the fruiting bodies of Tylopilus eximius. Their structures were elucidated on the basis of spectroscopic analyses (1D and 2D NMR data and ROESY correlations) and X-ray crystallography. Each racemate was separated into its individual enantiomers, and electronic circular dichroism calculations were used to assign the absolute configuration of (+)- and (-)-tylopilusin A (1) and (+)- and (-)-tylopilusin B (2).
