  Copper-Mediated Synthesis of Substituted 2-Aryl-N-benzylbenzimidazoles and 2-Arylbenzoxazoles via C–H Functionalization/C–N/C–O Bond Formation

  摘要：

  An efficient method for the transformation of N-benzyl bisarylhydrazones and bisaryloxime ethers to functionalized 2-aryl-N-benzylbenzimidazoles and 2-arylbenzoxazoles is described. The protocol involves a copper(II)-mediated cascade C-H functionalization/C-N/C-O bond formation under neutral conditions. Substrates having either electron-donating or -withdrawing substituents undergo the cyclization to afford the target heterocycles at moderate temperature.

  Development of sustainable methods for the activation of less reactive undirected C(sp³)–H bonds is challenging but desired in organic synthesis. The present manuscript demonstrates selective activation of acidic C(sp³)–H groups for a dehydrogenative C–H imination reaction by 4H elimination using PhI (10 mol%)–mCPBA as an organocatalyst.

  开发可持续方法来活化较不活泼的无向C(sp³)–H键在有机合成中具有挑战性但是受欢迎。本手稿展示了使用PhI (10 mol%)–mCPBA作为有机催化剂进行脱氢C–H亚胺化反应，实现对酸性C(sp³)–H基团的选择性活化。
