Description	The acylation of substituted 2-aminopropanamides with (2S)-Boc-proline, (2S)-Cbz-proline and (2S)-Bn-proline was used to prepare substituted 1-protected N-(1-carbamoyl-1,1-dialkyl-methyl)-(S)-prolinamides (74-89%), whose subsequent deprotection gave N-(1-carbamoyl-1,1-dialkyl-methyl)-(S)-prolinamides (94-95%). The enantiomerically pure N-(1-carbamoyl-1,1-dialkyl-methyl)-(S)-prolinamides obtained were tested as organocatalysts for the aldol reaction of cyclohexanone with 4-nitrobenzaldehyde, with yields ranging from 38% to 79% ee.
