A palladium-catalyzed 1,4-carboamination of bromoarenes with diazo compounds and amines was developed. This reaction proceeds through a palladium-carbene that then generates a π-benzylpalladium intermediate, forming ipso C–C and para C–N bonds on bromoarenes in a regioselective manner. The successful application of this transformation to the rapid synthesis of an antitumor agent demonstrates its synthetic
开发了钯催化的溴代芳烃与重氮化合物和胺的 1,4-羰基化反应。该反应通过钯-卡宾进行,然后生成 π-苄基钯中间体,以区域选择性的方式在溴芳烃上形成同样的 C-C 和对 C- N键。这种转化成功地应用于抗肿瘤药物的快速合成证明了它的合成效用。
