An efficient catalytic asymmetric synthesis of chiral γ-butenolides was developed based on the hetero-allylic asymmetric alkylation (h-AAA) in combination with ring closing metathesis (RCM). The synthetic potential of the h-AAA-RCM protocol was illustrated with the facile synthesis of (−)-whiskey lactone, (−)-cognac lactone, (−)-nephrosteranic acid, and (−)-roccellaric acid.
基于杂烯丙基不对称烷基化反应(h -AAA)结合闭环复分解(RCM),开发了一种高效的手性γ-丁烯内酯催化不对称合成方法。h -AAA-RCM协议的合成潜力通过(-)-威士忌内酯,(-)-科涅克白兰地内酯,(-)-肾甾烷酸和(-)-酒石酸的轻松合成得到了说明。
