example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-coupling reactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong
报道了芳基碘化物与胺的辅助(P,N)-配体使能的金催化的CN交叉偶联反应的第一个例子。在从头合成,后期修饰和级联过程中获得官能化的吲哚酮和咔唑的反应具有很高的通用性,这突出了所提出策略的合成潜力。用ESI-HRMS和NMR监测反应为原位形成假定的高价Au(III)中间体提供了有力的证据。
