versatile copper catalyzed one‐pot synthesis of diversely substituted pyrimidines directly fromamides, 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
