A simple and efficient method has been developed for the preparation of primary oxamates and α-ketoamides through the oxidative coupling of diazo compounds and NH4I. Under the optimized reaction conditions, a range of diazoesters and α-diazoketones was explored, and the corresponding products were obtained in moderate to good yields. This protocol is metal-free, is performed under mild conditions, has a wide substrate scope, and offers operational simplicity.
1,2-dicarbonyl compound and synthesis method thereof

Paragraph 0055-0060, (2019/10/01)
The invention discloses a method for synthesizing a 1,2-dicarbonyl compound (1,2-dicarbonylamide or alpha-diketone compound), wherein 1,2-dicarbonyl thioester compounds used as 1,2-dicarbonyl reagentsreact with amine compounds or boric anhydride compounds under appropriate conditions to respectively synthesize a series of 1,2-dicarbonyl compounds. According to the present invention, the 1,2-dicarbonyl compound is obtained by using the stable 1,2-dicarbonyl thioester compound as the dicarbonylation reagent through one-step construction under mild conditions, such that the disadvantage that thetraditional method uses the unstable alpha-carbonyl acyl chloride to synthesize the 1,2-dicarbonyl compound is avoided.
