The asymmetric synthesis of (S)-2-sec-butyl-4,5-dihydrothiazole, one of the pheromone components of the male mouse, Mus musculus, has been achieved by induction of chirality through stereoselective alkylation reaction using non-cross-linked polystyrene (NCPS) supported 2-phenylimino-2-oxazolidine as a chiral auxiliary. This method is efficient, and the chiral auxiliary can be recovered by simple filtration
(S)-2-sec-丁基-4,5-二氢噻唑是雄性小鼠 Musculus 的信息素成分之一,通过立体选择性烷基化反应诱导手性实现了不对称合成。聚苯乙烯 (NCPS) 支持 2-苯基亚氨基-2-恶唑烷作为手性助剂。这种方法效率高,手性助剂可以通过简单的过滤回收。最终产品的 ee 为 91%,总产率为 23%。
