β-Chloroamine hydrochlorides, produced stereospecifically and regiospecifically from aziridines with anhydrous hydrogen chloride in ether, are condensed with sodium carbonate in dry DMSO to afford isomerically pure 2-oxazolidinones.

range of functionaloxazolidinones is reported. The method is based on cheap and readily available starting materials including terminal and internal (bicyclic) epoxides and phenyl carbamate. The oxazolidinones serve as highly useful synthons for the high yield preparation of non‐symmetrical ureas by nucleophilic ring‐opening affording the targeted urea compounds with excellent functional group diversity
