Article abstract of DOI:10.1016/S0040-4039(00)94482-4

A wide variety of β-aminoesters are prepared in good yields by the reaction of lithium ester enolates derived from ketene silyl acetals with N-(alkylamino)benzotriazoles. The secondary β-aminoesters readily cyclize to β-lactams (2-azetidinones) on deprotonation.
