Asymmetric synthesis of monocyclic β-lactams: Application of imines derived from chiral N-protected α-amino aldehydes in the staudinger reaction

Imines derived from N,O-diprotected L-serinal upon treatment with acid chlorides in the presence of triethylamine furnished β-lactams with complete level of reaction diastereoselection.
