  Copper-Catalyzed Intramolecular Cyclization ofN-Propargyl-Adenine: Synthesis of Purine-Fused Tricyclics

  摘要：

  A novel protocol to construct fluorescent purine-fused tricyclic products via intramolecular cyclization of N-propargyl-adenine has been developed. With CuBr as the catalyst, a series of purine-fused tricyclic products were obtained in good to excellent yields (19 examples, 75-89% yields). When R-2 was a hydrogen atom in N-propargyl-adenines, the reactions only afforded the endocyclic double bond products. When R-2 was an aryl group, the electron-onating groups favored the endocyclic double bond products, while the electron-withdrawing groups favored the exocyclic double bond products.
