simple and efficient one-pot three-component synthesis of pyrrolo[1,2-c]pyrimidine derivatives starting from various substituted pyrimidines, 2-bromoacetophenones, and electron deficient alkynes in epoxides acting both as reaction medium and HBr scavanger. This method proved to be very lucrative and avoids formation of ylide inactivation products. The synthesis represents an environmentally benign alternative
本文报道了一种简单,高效的一锅三组分合成吡咯并[1,2-c]嘧啶衍生物的方法,该衍生物由各种取代的嘧啶,2-溴苯乙酮和缺电子炔烃组成,它们分别用作反应介质和HBr自由基。该方法被证明是非常有利可图的,并且避免了形成内鎓盐灭活产物。该合成代表了传统方法在环境上的良性替代。关于改进的Lipinski规则简要评估了新的化合物库,以评估化合物的潜在药物似然性。大多数化合物都符合Lipinski规则。
