An efficient and practical method was developed for the synthesis of tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones based on the decarboxylative cyclization reaction of α-ketoamides and proline. In most cases, tetrahydro-1H-pyrrolo[1,2-a]imidazol-2-ones were obtained with perfect diastereoselectivity to give trans-isomer in excellent yield.

A catalyst- and additive-free chemoselective transfer hydrogenation of α-keto amides to α-hydroxy amides is easily achieved by using sodium formate as a hydrogen source. The utility of this method is demonstrated by gram-scale synthesis and transformation of the resultant α-hydroxy amides into polysubstituted acetamides and 2-arylindole derivatives. Control experiments suggest that the NH group of α-keto amides is crucial for the chemoselective reduction through the formation of hydrogen bonds.
