Abstract

Chiloscypholone, a bicyclic sesquiterpenoid from the liverwort Chiloscyphus pallescens, is shown to have the structure (3), with a novel ring-contracted eremophilane skeleton, on the basis of chemical and spectroscopic (mainly from 1H and 13C n.m.r. spectra) evidence; dehydration of (3) gives two isomeric dienones, one of which is chiloscyphone, originally isolated from C. polyanthus, now assigned the revised structure (4).
