Pd-catalyzed allylations are excellent tools for stereoselective peptide modifications, showing several advantages compared to normal alkylations. Reactions of internal peptide amide enolates with Pd–allyl complexes proceed not only with high yields of up to 86%, they show also high regio- and diastereoselectivities (88–99%), giving rise to the trans-configured products. Therefore, this protocol is
Pd催化的烯丙基化是进行立体选择性肽修饰的极佳工具,与常规烷基化反应相比,显示出一些优势。内部肽酰胺烯醇化物与Pd-烯丙基复合物的反应不仅产率高达86%,而且还具有很高的区域选择性和非对映选择性(88-99%),从而产生了反式构型的产物。因此,该协议是用于合成天然产物和药物分子的强大合成工具。
