(E,Z)-2,4-Hexadiene was transformed to the lactone cis-1 ( ⪢ 93% cis)(pheromone of the carpenter bee) in a stereospedfic reaction sequence via a Pd-calalyzed 1,4-acetoxychlorination. The same reaction sequence applied to (E,E)-2,4-hexadiene afforded the isomeric lactone trans-1 (⪢91% trans).
(E,Z)-2,4-己二烯转化成内酯顺- 1(⪢93%顺式在stereospedfic反应序列)(木匠蜂的信息素)经由一个钯calalyzed 1,4- acetoxychlorination。相同的反应顺序施加到(E,E)-2,4-己二烯,得到同分异构的内酯反式- 1(⪢91%反式)。
