Secondary mould metabolites. Part 29. Isolation and structure elucidation of candicansol, 3-epi-illudol and 1-O-acetyl-3-epi-illudol, novel sesquiterpenoids from Clitocybe candicans, and absolute configuration of 3-epi-illudol

Abstract

The structural elucidation of candicansol (1a), 3-epi-illudol (2a), and 1-O-acetyl-3-epi-illudol (3), novel illudalane and protoilludane sesquiterpenoids isolated from cultures of Clitocybe candicans is based on a study of their ¹H and ¹³C n.m.r. spectral data. The absolute configuration of 3-epi-illudol is also reported.
