A highly efficient and concise synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate (1) and (3E,8Z)-tetradeca-3,8- dienyl acetate (2), both sex pheromone components of the tomato leafminer Tuta absoluta was achieved. The stereoselective formation of the 8Z-double bond was accomplished by a Wittig reaction and the 3E-double bond was formed by a modified Knoevenagel condensation. Pheromones 1 and
(3 E ,8 Z ,11 Z )-tetradeca-3,8,11-trienyl acetate ( 1 ) 和 (3 E ,8 Z ) -tetradeca-3,8- dienyl acetate ( 2 )的高效、简洁合成),番茄潜叶虫Tuta absoluta的两种性信息素成分都得到了实现。8 Z-双键的立体选择性形成通过Wittig反应完成,3 E-双键通过修饰的Knoevenagel缩合形成。信息素1和2以高立体化学纯度获得,并且从市售的1,6-己二醇开始,总收率分别为34.7%和37.6%。
