    Copper Catalyzed N-Arylation of Amidines with Aryl Boronic Acids and One-Pot Synthesis of Benzimidazoles by a Chan–Lam–Evans N-Arylation and C–H Activation/C–N Bond Forming Process
    摘要:
    Mono-N-arylation of benzamidines 1 with aryl boronic acids 2 was effectively achieved in the presence of a catalytic amount of Cu(OAc)(2) and NaOPiv under mild aerobic conditions. Combining this step with an intramolecular direct C-H bond functionalization, catalyzed by the same catalytic system but under oxygen at 120 degrees C, afforded benzimidazoles 3 in good to excellent yields.

  • Substrate-controlled Rh(<scp>iii</scp>)-catalyzed regiodivergent annulation towards fused and spiro benzimidazoles
    作者:Ying-Ti Huang、Indrajeet J. Barve、Yi-Ting Huang、Sandip Dhole、Wei-Jung Chiu、Chung-Ming Sun

    Mechanistically, C–H activation followed by migratory insertion of maleimide forms a Heck-type intermediate. Unsubstituted benzimidazole undergoes aza-Michael addition to form a (4 + 2) fused product, whereas ortho-substituted phenyl benzimidazole causes steric clash to deliver a (4 + 1) spiro-adduct favorably via acid-catalyzed intramolecular annulation.
    报道了 Rh( III ) 催化的 2-芳基苯并咪唑与马来酰亚胺的级联 C-H 活化和环化,用于合成苯并咪唑稠合异喹啉和苯并咪唑螺环异吲哚。在苯环的邻位使用未取代和取代的苯并咪唑可以实现对这两种不同产物形成的可转换选择性。从机制上讲,C-H 活化后迁移插入马来酰亚胺形成 Heck 型中间体。未取代的苯并咪唑通过氮杂-迈克尔加成形成 (4 + 2) 稠合产物,而邻位取代的苯基苯并咪唑引起空间冲突以有利地提供 (4 + 1) 螺加合物酸催化的分子内环化。
