Three approaches to the enantioselective synthesis of 3-amino-4-substituted-2-azetidinones by condensation of α-amino ester enolates with imines are described: (i) application of chiral ester derivatives of N,N-diethylglycine; (ii) application of chiral N

A synthesis of trans-β-lactams with an easily convert-ible group on the C-4 carbon atom of the azetidinone ring comprising a condensation reaction of a metal enolate with an imine with a heterocyclic group or a diimine is provided. Furthermore, new chiral
