  Ligand-Free Copper-Catalyzed Arylation of Amidines

  摘要：

  Copper-catalyzed cross-coupling reactions of amidine salts were utilized to synthesize monoarylated amidines in moderate to high yields with ligand-free conditions. DMF was the superior solvent for the N-arylation of benzamidines, while MeCN was used in the formation of N-aryl amidines in moderate to high yield.

  We report a novel and practical one-pot Rh(III)-catalyzed strategy to construct benzimidazo[1,2-a]quinolines from readily available imidamides and anthranils. The cascade reaction proceeds via a C-H amination-cyclization-cyclization process in ionic liquid without any additives and possesses simple operation, moderate-to-high yield, and broad substrate scope features, which will provide the reference

  The synthesis of N-unprotected indoles has been realized via Rh(III)-catalyzed C–H activation/annulation of imidamides with α-diazo β-ketoesters. The reaction occurs with the release of an amide coproduct, which originates from both the imidamide and the diazo as a result of C═N cleavage of the imidamide and C–C(acyl) cleavage of the diazo. A rhodacyclic intermediate has been isolated and a plausible

  N-未保护的吲哚的合成已通过Rh（III）催化的C-H活化/亚酰胺与α-重氮β-酮酸酯的环化而实现。反应发生时会发生酰胺副产物的释放，酰胺副产物既来自亚酰胺也来自重氮，这是由于亚胺的C═N裂解和重氮的C–C（酰基）裂解所致。分离了一个rhodocyclic中间体，并提出了一个合理的机制。

  An efficient synthesis of 2-substituted quinolines from readily available cyclopropanols and imidamides has been developed, where the cyclopropanol acts as a C3 synthon. With the assistance of a bifunctional imidamide directing group, the reaction occurred via sequential C–H/C–C cleavage and C–C/C–N bond formation.

  We described an Rhodium(III)-catalyzed divergent C−H bond functionalization of N-aryl amidines with iodonium ylides. Carbazolones and zwitterionic salts were diversely constructed through intermolecular annulation and intramolecular proton transfer under the different reaction conditions. This protocol is operationally simple and tolerates a variety of functional groups. The efficient post-modification
