  Asymmetric Synthesis of .beta.-Lactams. Highly Diastereoselective Alkylation of Chiral 2-Cyano Esters

  摘要：

  Enolates derived from 10-(dicyclohexylsulfamoyl)isobornyl 2-substituted-2-cyanoacetates were alkylated with very good yield and high diastereoselectivity. The reduction of the resulting reaction products and subsequent cyclization of the p-amino acids led to the corresponding beta-lactam in high yields. This result paves the way for the development of a versatile and efficient asymmetric synthesis of enantiomerically pure (R)- and (S)-C(3)-disubstituted beta-lactams.
