Concise and efficient syntheses of (7Z,11Z,13E)-hexadecatrienal, a sex-pheromone component of the citrus leaf miner, and (8E,10Z)-tetradecadienal, the sex pheromone of the horse-chestnut leaf miner were described, starting from the commercially available acetylene and acrolein. The stereoselective formation of E,Z-conjugated double bond relied on cross-coupling between Grignard reagent and (E,Z)-bromodiene. The present syntheses achieved high overall yield (26% of the former and 23% for the latter) and high isomeric purity (97% for the former and 99% for the latter).
简明有效地合成了柑橘叶虫的性信息素成分(7Z,11Z,13E)-十六碳三烯醛和马栗叶虫的性信息素(8E,10Z)-十四碳二烯醛,起始原料为商业可获得的乙炔和丙烯醛。E,Z-共轭双键的立体选择性形成依赖于Grignard试剂与(E,Z)-溴二烯的交叉偶联。当前的合成实现了高的总体产率(前者26%,后者23%)和高的异构体纯度(前者97%,后者99%)。
