Isolation and structure of dictyoprolene, a possible precursor of various undecanes in brown algae from Dictyopteris prolifera

Abstract

The isolation and structure elucidation (including the absolute stereochemistry) of (+)-dictyoprolene (1) a constituent of Dictyopteris prolifera, together with the synthesis of (1) in optically active form indicate that (1) is the acetate of one of three undec-1-en-3-ols postulated to be key biosynthetic intermediates leading to various novel C₁₁ hydrocarbons in Dictyopteris.
