N‐diethylarylamide using CIPE‐assisted α‐silyl carbanions (CIPE=complex‐induced proximity effect) has been developed using a simple reagent combination of LDA (lithium diisopropylamide) and chlorosilane. A study of the mechanism, and the application of the procedure to an anionic Snieckus–Fries rearrangement for a highly efficient synthesis of the potent phosphatidylinositol 3‐kinase (PI3K) inhibitor LY294002
使用LDA(二异丙基锂酰胺)和氯硅烷的简单试剂组合,开发了使用CIPE辅助的α-甲硅烷基碳负离子对N,N-二乙基芳基酰胺进行羟基定向的烷基化反应(CIPE =络合物诱导的邻近效应)。报道了对该机理的研究,以及该方法在阴离子Snieckus-Fries重排中的应用,以高效合成强效磷脂酰肌醇3-激酶(PI3K)抑制剂LY294002。
