Dolabellol A, a new halogenated diterpene isolated from the opisthobranch dolabella auricularia

Abstract

A new halogenated diterpene, dolabellol A (1), was isolated from the opisthobranch Dolabella auricularia. The planar structure of dolabellol A was elucidated by NMR spectroscopic analysis and chemical reactions. The absolute stereochemistry was determined by single-crystal X-ray diffraction studies.
