Isocedrene and guaiane derivatives from pleocarphus revolutus

Abstract

A reinvestigation of the aerial parts of Pleocarphus revolutus afforded, in addi tion to sesquiterpenes isolated previously, four new guaiane derivatives and four isocedrene derivatives, one of which is new. Furthermore, the configuration of the guaiane 5 has been revised. The structures were established by high field nmr spectroscopy. © 1988, American Chemical Society. All rights reserved.
