A novel and practical method has been developed for the preparation of α-keto amides by a catalyst-free aminocarbonylation of carboxylic esters with N,N-dimethylcarbamoyl(trimethyl)silane under neutral conditions. A new protocol for the synthesis of vicinal tricarbonyl compounds was also developed by using this method. In the case of diesters, only one ester group reacted selectively with 1.2 equivalents
