method for the direct methylation of aryl, heteroaryl, and vinyl boronate esters is reported, involving the reaction of iodomethane with aryl-, heteroaryl-, and vinylboronate esters catalyzed by palladium and PtBu2Me. This transformation occurs with a remarkably broad scope and is suitable for late-stage derivatization of biologically active compounds via the boronate esters. The unique capabilities
报道了一种使芳基,杂芳基和乙烯基硼酸酯直接甲基化的方法,该方法涉及碘甲烷与由钯和PtBu 2 Me催化的芳基,杂芳基和乙烯基硼酸酯的反应。这种转化发生的范围非常广,并且适合于通过硼酸酯进行生物活性化合物的后期衍生化。通过串联形成碳-硼键形成反应和钯催化的甲基化反应,证明了该方法的独特功能。
