Revision of the Structure of the Major Aggregation Pheromone of the Broad-horned Flour Beetle (Gnatocerus cornutus) to (1S,4R,5R)-α-Acoradiene by Its Synthesis

Abstract

(1S,4R,5R)-(+)-α-Acoradiene [1,8-dimethyl-4-(1-methylethenyl)spiro[4.5]dec-7-ene] (1) is shown by its synthesis to be the major component of the male-produced aggregation pheromone of the broad-horned flour beetle (Gnatocerus cornutus).
