摘要：

A highly efficient and selective synthesis of enamides via C-H amidation of N-methoxy acrylamides with dioxazolones is realized under [Cp*Co-III] catalysis. The resulting enamide can further selectively cyclize to form pyrimidones, which can also act as a directing group for a second C-H amidation. All these three classes of products were selectively delivered under controlled conditions.
