Abstract

Abstract The structure of three new drimane sesquiterpenes ( 1–3) has been established from chemical and spectroscopic evidence and by single crystal X-ray crystallographic analysis of 7. Ring B in the crystal of 7 is in a chair conformation, slightly distorted because of cis fusion to the lactone ring and because three β axial substituents are present. NMR evidence suggests that the preferred conformation in solution is similar.
