✦ Synopsis

Abstract

A fast and highly regio‐ and stereoselective transformation of non‐conventional β‐lactam‐containing epoxides into the corresponding cyclic 1,3‐dioxolanes and oxazolines is herein reported, using microwave irradiation as an efficient source of energy, in the presence of stoichiometric or catalytic amounts of Lewis acids, without an additional solvent. These cyclic compounds are the protected forms of diols and amino alcohols.
