by rhodium-catalyzed C–H functionalization of indoles with acryloyl silanes was developed, providing a convenient and highly effective method for the synthesis of functionalized acylsilane derivatives. By tuning the reaction condition, this C–H-activation-initiated reaction proceeds divergently with acryloyl silianes to selectively afford alkylation or alkenylation products via hydroarylation or oxidative
通过铑催化丙烯腈对吲哚的C–H官能化,开发了一种协议,为合成官能化的酰基硅烷衍生物提供了一种方便而高效的方法。通过调节反应条件,这种由C–H活化引发的反应与丙烯酰基甲硅烷分叉进行,分别通过加氢芳基化或氧化交叉偶联选择性地提供烷基化或烯基化产物。在这两种情况下采用的温和的反应条件均允许宽范围的功能性以及高的反应效率。此外,通过可见光诱导的反应级联,很容易从2-烯基化产物中获得多环吲哚衍生物。
