YieldReaction ConditionsOperation in experiment
With triethylamine; In dichloromethane; at 0 - 20℃; for 4h; General procedure: To a solution of alpha-ketoacids (1.0 eq., 0.5 M) in DCM was added a drop of DMF at room temperature followed by the addition of oxalyl chloride (1.2 eq.). The resulting mixture was stirred at this temperature until no gas was released. The reaction mixture was subsequently cooled to 0oC followed by the addition of amine (1.2 eq.) and Et3N (2.0 eq.). The resulting reaction mixture was warmed to room temperature and stirred for 4 h. After addition of water (5 mL), the mixture was washed with 1N HCl and water respectively and dried over Na2SO4. Purification by flash column chromatography afforded the desired alpha-ketoamides.

YieldReaction ConditionsOperation in experiment
With triethylamine; In dichloromethane; at 0 - 25℃; for 12.25h;Inert atmosphere; To a stirred solution of N-methyl pyrrol i din- 3-ol (2, 1 equiv) and Et3N (1.2 equiv) in dichloromethane was added a solution of 2- oxo-2- phenyl acetyl chloride (1.1 equiv) in dichloromethane at 0 °C under nitrogen atmosphere for 15 min. The resulting solution was allowed to stir at room temperature over 12h. After completion, the mixture was quenched with water and extracted with diethyl ether to afford the pure product (3B). (0044) Similarly, the product 3B is also obtained by reaction of 2 with other reagents, phenyl oxalic acid, methyl phenyl oxalate, and phenyl hemi-oxaldehyde respectively as shown in Scheme 2.
