STEREOSELECTIVE ONE-POT SYNTHESES OF TRANS-3-AMINO-β-LACTAMS FROM ZINC ENOLATES OF N-PROTECTED α-AMINOACID ESTERS AND IMINES

A new one-pot synthesis of 3-amino-β-lactams that is based on the condensation of simple imines with zinc enolates of disilyl protected glycine esters is reported.Isolated yields are high and a trans-selectivity is observed.
