Ferrubietolide: X-ray crystal structure of a novel bis-diterpene from Dysoxylum Ienticellare

Abstract

Spectroscopic and X-ray diffraction analyses have established the structure and stereochemistry of ferrubietolide, a new bis-diterpene isolated from Dysoxylum Ienticellare, which apparently arises as the result of a Diels–Alder condensation of two dissimilar diterpenes.
