The first highly enantioselective iridium‐catalyzed allylic alkylation that provides access to products bearing an allylic all‐carbon quaternary stereogenic center has been developed. The reaction utilizes a masked acyl cyanide (MAC) reagent, which enables the one‐pot preparation of α‐quaternary carboxylic acids, esters, and amides with a high degree of enantioselectivity. The utility of these products
已开发出首个高度对映选择性的铱催化的烯丙基烷基化反应,该反应可提供带有烯丙基全碳季立体中心的产物。该反应利用一种掩蔽的酰基氰(MAC)试剂,该试剂可以一锅制备具有高对映选择性的α-季羧酸,酯和酰胺。通过一系列不同的产品转换,可以进一步探索这些产品的实用性。
