(+)-Disparlure, the sex attractant emitted by the female gypsy moth, Portheriadispar (L.), and its (−)-enantiomer were synthesized in 43% yield and >99% ee, starting from undecanal and using the asymmetric dihydroxylation (AD) reaction. Similarly, the two trans-isomers of disparlure were synthesized in 51% yield and 95% ee.
(+)-Disparlure,雌性吉普赛蛾发出的性诱剂Portheria dispar(L.)及其(-)-对映异构体的合成方法是,从十一碳开始,并使用不对称二羟基化反应,产率为43%,ee> 99% (AD)反应。类似地,以51%的收率和95%的ee合成了两种不同的反式异构体。
