    Project supported by the National Natural Science Foundation of China (Nos. U1204204, 21172139, 21202095), the Science and Technology Key Project of Henan Province (No. 142102210635), and the Program for University Key Young Teachers of Henan Province (No. 2015GGJS-126).

A series of α-ketoamide derivatives were obtained from the palladium catalyzed oxidation of ynamides using cheap and readily available dimethyl sulfoxide as oxidant and solvent under room temperature. The structures of all products were characterized by 1H NMR, 13C NMR, IR and HRMS. This protocol has some distinct advantages of mild conditions, simple work-up, readily available starting materials and fast reaction rate.

Key words: dimethyl sulfoxide, ynamides, α-ketoamides, synthesis, oxidation
