• Pd-Catalyzed C-3 functionalization of indolizines via C–H bond cleavage
  作者：Baoli Zhao

  DOI：10.1039/c2ob25643f

  日期：——

  New transition metal-catalyzed methods for the arylation of indolizines by the direct cleavage of C–H bonds have been developed. A wide range of aryltrifluoroborate salts react with indolizines in the presence of Pd(OAc)2 catalyst and AgOAc oxidant to give the arylated indolizines in high yields. Both electron-donating and electron-withdrawing groups perform smoothly while bromide and chlorine substituents are tolerated. In addition, the indolizines display similar reactivities in the Pd-catalyzed reaction with 3-phenylpropiolic acid to afford the corresponding C-3 alkynylated indolizines. These methods allow the direct functionalization of indolizines in one step.

  开发了新的过渡金属催化方法，通过直接断裂C-H键实现吲哚并环己烯的芳基化。一系列芳基三氟硼酸盐在Pd(OAc)2催化剂和AgOAc氧化剂的存在下与吲哚并环己烯反应，高效地得到芳基化的吲哚并环己烯。供电子和吸电子基团均表现良好，而溴和氯取代基也可耐受。此外，吲哚并环己烯在Pd催化反应中与3-苯基丙炔酸显示出相似的反应活性，从而获得相应的C-3炔基化吲哚并环己烯。这些方法使得吲哚并环己烯能够在一步中直接进行官能团化。
