of enamides with formamides is described. Routing from readily accessible feedstocks, the efficient approach is implemented to furnish a broad array of value-added N-acyl enamine amide derivatives, which serve as versatile precursors of biologically relevant N-heterocycles including pyrimidin-4-ones and 4-hydroxypyridin-2-ones. Preliminary mechanistic studies supported the notion that this direct carbamoylation
