AlCl3 facilitated C–C bond forming reaction between 4-chloro-thieno[2,3-d]pyrimidines and (hetero)arenes affording a direct and single-step method for the synthesis of 4-(hetero)aryl substituted thieno[2,3-d]pyrimidines. A number of novel thienopyrimidines were prepared in good to excellent yields using this methodology. The molecular structure of a representative compound was established unambiguously
AlCl 3促进4-氯-噻吩并[2,3- d ]嘧啶与(杂)芳烃之间的CC键形成反应,为合成4-(杂)芳基取代的噻吩并[2]提供了直接而又一步的方法。 ,3- d ]嘧啶。使用这种方法可以制备许多新颖的噻吩并嘧啶,收率良好。通过单晶X射线衍射明确地建立了代表性化合物的分子结构。
