摘要

The thermolysis of ethyl azidoformate in acetic and propionic anhydrides as solvents yielded the corresponding N-acyl-2-oxazolidinones (2 a, b) in relatively significant yields. The other major products isolated were N-carboxyethyl-N, O-diacyl hydroxylamine (1 a, b) and N, N, O- triacetyl hydroxylamine (3), The intramolecular cyclization is facilitated by the solvent.
