Tsugicoline E, a New Polyoxygenated Protoilludane Sesquiterpene from the Fungus <i>Laurilia tsugicola</i>

Abstract

Tsugicoline E (3) has been isolated from cultures of the Basidiomycetous fungus Laurilia tsugicola and its structure deduced from 1H and 13C NMR and single-crystal X-ray diffraction studies. The suggested absolute configuration is consistent with biogenetic considerations.
