摘要：

A pheromone roughly 100 times more effective than cyclohepta‐1,4‐diene 2 (R = C2H5, ectocarpene) is its biosynthetic precursor 1. This thermally labile cis‐disubstituted cyclopropane is the actual signaling agent of the marine brown algae Ectocarpus siliculosus. The [3,3]sigmatropic rearrangement of 1 giving 2 (t1/2 = 21 min at 18°C) is the fastest known reaction for the spontaneous inactivation of a pheromone. (Figure Presented.)
