Abstract

Desmarestene 1 6‐(1__Z__,3‐butadienyl)‐1,4‐cycloheptadiene and viridiene 3 cis‐3‐(1__Z__, 3‐butadienyl)‐4‐vinylcyclopentene are chemical messengers for male gametes of the brown algae Desmarestia aculeate and Desmarestia viridis. Total syntheses of 1, 3 and their stereoisomers 1a, 3ac are reported. Gas‐chromatographic comparison of synthetic 1 and 3 with the corresponding natural products has established their structural identity.

Introduction. ~ During sexual reproduction, fertile female gametes of the marine brown alga Perithalia caudata release caudoxirene (1) as a specific chemical messenger. The signal is secreted together with two inactive by-products, namely viridiene (2, ca. 4%) and multifidene (3, ca. 8%) [l] [2] (Sc
