The first general method for the synthesis of α-alkyl ynones was developed based on the strategy of electrophilic activation of amides. Its distinctive advantages are attributed to the use of air-stable “bare” 1-copper(I) alkyne as a mild nucleophile without any exogeneous ligand.
基于酰胺的亲电活化策略,开发了第一种合成α-烷基炔酮的通用方法。它的独特优势归因于使用空气稳定的“裸” 1-铜(I)炔烃作为温和的亲核试剂,没有任何外源性配体。
