3-Acetoxyspathulenol, a New Aromadendrane-Type Natural Product from the Soft Coral <i>Parerythropodium fulvum</i>

Abstract

From the lipophilic extract of the soft coral Parerythropodium fulvum a new sesquiterpene with an aromadendrane-type carbon skeleton, 3-acetoxyspathulenol (1), was isolated, and the known compounds spathulenol (2) and tridensenone (3) were identified. The structure of the new compound was determined by interpretation of its spectroscopic data, including 1D and 2D (1)H and (13)C NMR (COSY, HMQC, HMBC) and MS.
