Expanding the Application Range of Aldolases: Novel Asymmetric Syntheses of α‐Methylated β‐Hydroxy α‐Amino Acids and β‐Amino Alcohols

Broadened horizons: The application range of the long-known enzymatic enantio- and diastereoselective synthesis of β-hydroxy α-amino acids, a structural motif widely found in drug molecules and their intermediates, by means of an aldol reaction has recently been successfully expanded towards the asymmetric synthesis of α,α-disubstituted β-hydroxy α-amino acids and β-amino alcohols.
