Synthesis of (+)-disparlure, 1, the sex pheromone of gypsy moth (Lymantria dispar), commenced from cis-vinyl epoxide 4 which was prepared by our asymmetric chloroallylboration in 99% de and 94% ee. Hydroboration of 4 using dicyclohexylborane in THF, followed by sodium perborate oxidation gave a crystalline cis-3,4-epoxy alcohol 3 whose enantiomeric purity was enhanced by recrystallization. Conversion
(+)-disparlure(1,吉普赛蛾(Lymantria dispar)的性信息素)的合成始于顺式-乙烯基环氧化物4,该环氧化物是由我们在99%de和94%ee中的不对称氯烯丙基化制得的。使用二环己基硼烷在THF中进行4硼氢化,然后用过硼酸钠氧化,得到结晶的顺式3,4-环氧醇3,其对映体纯度通过重结晶得到增强。3到(+)-disparlure的转化是通过甲苯磺酸酯的烷基化。分四步生产(+)-Disparlure,总产率为27%,ee> / = 99.5%。
