  Rhodium(III)-Catalyzed Direct Selective C(5)–H Oxidative Annulations of 2-Substituted Imidazoles and Alkynes by Double C–H Activation

  摘要：

  Double C-H activations of C(5)-H and Csp(2)-H of 2-substituted N-vinyl- or arylimidazoles were realized without heteroatom-directing assistance by rhodium(III) catalyst. A subsequent oxidative annulation reaction with alkynes efficiently produced aza-fused heterocycles with high molecular complexity in low to excellent yields.

  A simple approach for synthesis of novel aza-fused scaffolds such as pyrido[1,2-α]benzimidazoles and imidazo[1,2-α]pyridines was developed by Rh(III)-catalyzed direct oxidative coupling between alkenes and unactivated alkynes without an extra directing group. The method would allow a broad substrate scope, providing fused heterocycles with potential biological properties.

  通过Rh（III）催化的烯烃与未活化炔烃之间的直接氧化偶联，开发了一种简单的合成新型氮杂稠合骨架的方法，如吡啶并[1,2- α ]苯并咪唑和咪唑并[1,2- α ]吡啶一个额外的指导小组。该方法将允许广泛的底物范围，提供具有潜在生物学特性的稠合杂环。
