A New Route to Enantiopure β‐Aryl‐Substituted β‐Amino Acids and 4‐Aryl‐Substituted β‐Lactams through Lipase‐Catalyzed Enantioselective Ring Cleavage of β‐Lactams
Abstract A simple and efficient direct enzymatic method was developed for the synthesis of 4‐aryl‐substituted β‐lactams and the corresponding β‐amino acid enantiomers through the CAL‐B (lipase B from Candida antarctica )‐catalyzed enantioselective ( E >200) ring cleavage of the corresponding race...
