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

A chemoselective electrooxidative heterocoupling of two different enamines is reported for the synthesis of unsymmetricallysubstituted NH-pyrroles. A “magic effect” of the additive trifluoroethanol is utilized to achieve the desired chemoselectivity by tuning the oxidation potentials and controlling the activation energy of the rate-determining step.
