A versatile copper catalyzed one-pot synthesis of diversely substituted pyrimidines directly from amides, N,N′-dimethylformamide dimethylacetal (DMF?DMA) and enamines has been established. The reaction involved the two C?N bonds and one C?C bond formation by formal [2+1+3] annulation approach to pyrimidines. This protocol is based on the use of readily available primary amides, DMF?DMA and enamines to install di- and tri-substituted pyrimidine structure with diverse functionality in one-pot manner, which makes this strategy to be appealing for the medicinal chemistry.
