A simple and practical method for α-ketoamide synthesis via a decarboxylative strategy of isocyanates with α-oxocarboxylic acids is described. The reaction proceeds at room temperature under mild conditions without an oxidant or an additive, showing good substrate scope and functional compatibility. Moreover, the applicability of this method was further demonstrated by the synthesis of various bioactive molecules and different application examples through a two-step one-pot operation.

Paragraph 0055; 0104-0107, (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.
