摘要

Abstract N-tert-Butoxycarbonylated 2-oxazolidinones and tetrahydro-2-oxazinones are smoothly cleaved to acyclic N-Boc-amino alcohols on treatment with catalytic amounts of cesium carbonate at room temperature. The versatility of the procedure is demonstrated in a facile cleavage of highly functionalized heterocycles without epimerization and β- elimination.
