  Substrate Control in Enantioselective and Diastereoselective Aldol Reaction by Memory of Chirality: A Rapid Access to Enantiopure β-Hydroxy Quaternary α-Amino Acids

  摘要：

  An asymmetric aldol reaction by memory of chirality is reported with a substrate control of stereoselectivity by aldehyde and rationalized. Starting from L-alanine, several diastereopure and enantioenriched beta-hydroxy quaternary alpha-amino acids have been obtained in three steps. The initial chirality of L-alanine is memorized through the dynamic axial chirality of tertiary aromatic amide.
