A palladium-catalyzed domino Heck cyclization/carbonylative Hiyama–Denmark cross-coupling reaction between alkene-tethered aryl iodides and silylcarboxylic acids is presented. This reaction proceeds well without toxic carbon monoxide (CO) gas and has good functional group tolerance, providing an alternative access to carbonyl-containing oxindoles. In this transformation, silylcarboxylic acids play
提出了一种钯催化的多米诺 Heck 环化/羰基化 Hiyama-Denmark 烯烃系芳基碘化物和甲硅烷基羧酸之间的交叉偶联反应。该反应在没有有毒一氧化碳 (CO) 气体的情况下进行得很好,并且具有良好的官能团耐受性,为含羰基羟吲哚提供了另一种途径。在这种转化中,甲硅烷基羧酸作为 CO 源和亲核试剂发挥双重作用。
