1,4-Addition of RLi, RMgX, and (RS) 2CHLi reagents to unsaturated amides 2a-c followed by α-alkylation is shown to constitute a general and efficient synthetic procedure for the formation of two CC bonds in a single step.
将RLi,RMgX和(RS)2 CHLi试剂1,4-添加到不饱和酰胺2a-c中然后进行α-烷基化反应,可构成一种通用有效的合成方法,可在单个反应中形成两个CC键步。
