(R)-4-Methyl-1-nonanol, the sexpheromone of the yellow mealworn (Tenebrio molitor L.), was synthesized with high stereoselectivity using (S)-4-benzyloxazolidinone as chiralauxiliary. The stereoselectivesynthesis was achieved by asymmetric Michael addition of organocopper reagent to N-crotoyloxazolidinone, and the target product was obtained in an overall yield of 41.8% over 7 steps.
(R)-4-Methyl-1-nonanol 是黄粉蚧 (Tenebrio molitor L.) 的性信息素,使用 (S)-4-benzyloxazolidinone 作为手性助剂以高立体选择性合成。通过有机铜试剂与N-巴豆酰恶唑烷酮的不对称迈克尔加成实现立体选择性合成,7步得到目标产物,总收率为41.8%。
