Control elements in the highly selective construction of contiguous tertiary and quaternary carbon centers by the tandem alkylation of α-alkylidene-γ-butyrolactone derivatives were studied. It is clarified that the stereochemical course of the reaction is rationalized by evaluating highly selective 1,2-, 1,3-, and 1,4-asymmetric inductions.
研究了通过α-亚烷基-γ-丁内酯衍生物的串联烷基化对连续的叔碳和叔碳中心进行高选择性构建的控制元素。可以通过评估高度选择性的1,2-,1,3-和1,4-不对称诱导来合理化反应的立体化学过程。
