An improved procedure for preparing 4Z-nonen-1-ol, a key intermediate in the synthesis of sex pheromones of cabbage moth and cotton bollworm, from the cyclic butadiene-isoprene dimer (1-methyl-1Z,5Z-cyclooctadiene) was developed. In this procedure, the peroxide product of regioselective partial ozonolysis (0.9 equiv of O3) of the codimer across the trisubstituted double bond is converted in one step
由环丁二烯-异戊二烯二聚体(1-甲基-1 Z,5 Z-环辛二烯)合成4 Z-壬烯-1-醇的一种改进方法,该化合物是卷心菜蛾和棉铃虫性信息素合成的关键中间体发展了。在此程序中,共聚二聚物通过三取代双键的区域选择性部分臭氧分解(0.9当量的O 3)的过氧化物产物可一步转化为具有NaBH(OAc)3的9-羟基-5 Z-壬烯-2-酮,不影响结构中存在或过程中形成的酮基的试剂。
