  General Approach for the Stereocontrolled Construction of the β-Lactam Ring in Amino Acid-Derived 4-Alkyl-4-carboxy-2-azetidinones

  摘要：

  The first general approach toward the asymmetric synthesis of 4-alkyl-4-carboxy-2-azetidinones derived from amino acids is described. The stereoselective construction of the beta-lactam ring was achieved through base-mediated intramolecular cyclization of the corresponding N-alpha-chloroacetyl derivatives bearing (+)- or (-)-10-(N,N-dicyclohexylsulfamoyl)isoborneol as chiral auxiliary (ee up to 82%).
