Palladium Catalyzed Oxidation of Ynamides Using Dimethyl Sulfoxide as Oxidant: A Facile Way to Synthesize alpha-Ketoamide Derivatives
CHINESE JOURNAL OF ORGANIC CHEMISTRY(2016)
摘要
A series of alpha-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 H-1 NMR, C-13 NMR, IR and HRMS. This protocol has some distinct advantages of mild conditions, simple work-up, readily available starting materials and fast reaction rate.
