Abstract

β-Lactams were prepared from imines and aryl-substituted acetic acids using T3P as an activating agent. In most cases, good to excellent yields were obtained (up to 93%) and the trans-β-lactam was the exclusive or major diastereoisomer (confirmed through analysis of <sup>1</sup>H NMR coupling constants and by X-ray crystallography).
