  Synthesis of (R)- 3-alkyl-3-benzyl-2-azetidinones in enantiomerically pure form

  摘要：

  The diastereoselective alkylation of the enolate of 10-dicyclohexylsulfamoylisobornyl 3-phenyl-2-cyanopropanoate is reported. This alkylation took place with very good yield and selectivity and the reaction product was reduced and cyclised to the corresponding beta-lactam in high yield.
