We have developed a visible light-induced photo-redox copper-catalyzed oxidative Csp2-H annulation (Friedel-Crafts-type cyclization) of amidines with terminal alkynes at room temperature to synthesize functionalized quinazolines. We report copp

A new strategy is developed for the synthesis of 1-aminoisoquinoline derivatives. This Rh(III)-catalyzed [4 + 2] annulation reaction employs benzamidines as efficient directing groups and the vinylene carbonate as an acetylene surrogate. Additionally, the reaction features broad substrate scopes and good yields, only producing carbonate anion as byproduct.

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 for the construction of biologically active fused benzimidazoles.
