[摘要]：Catalytic nucleophilic addition to the carbon-nitrogen double bond of an imino group in an asymmetric fashion provides a direct connective and attractive route to enantioenriched N-protected amines with structural diversity. In the last decades, significant achievements have been made in the field of catalytic enantioselective reactions involving the use of alpha-amido sulfones as in situ equivalents of activated imines. These, in combination with diverse nucleophiles, are used to prepare optically pure amines or N-protected amides. This review focuses on the recent advances in the synthetic applications of alpha-amido sulfones as reactive precursors of imines in the asymmetric addition of organometallic reagents, Mannich, aza-Henry, Strecker, and other asymmetric nucleophilic addition reactions. |
