still problematic. In this communication, a silver‐catalyzed carbon‐phosphorus functionalization for polyheterocycle formation is described that furnishes good diastereoselectivity. Various substituted 1‐(1H‐indol‐1‐yl)‐3‐phenylprop‐2‐en‐1‐ones and phosphine oxides were suitable for this transformation. This work avoids the installation of direct functional groups and thus makes full use of shorter and
利用自由基过程以高非对映选择性构建多杂环仍然是有问题的。在本文中,描述了

磷官能团用于多杂环的形成,具有良好的非对映选择性。各种取代的1-(1 H-
吲哚-1-基)-3-苯基丙-2-烯-1-酮和氧化膦均适用于该转化。这项工作避免了直接官能团的安装,从而充分利用了更短,更有效的合成方法。初步的机理研究表明,
