Treatment of 4-alkoxy-6-methylpyrimidine 1-oxides with acetic anhydride followed by reaction with diketene gave 7-acetyl-4-alkoxy-2-methylisoxazolopyridines and 7-acetyl-4-alkoxy-3-methyloxazolopyridines, respectively.The structure elucidation of these compounds on the basis of spectral data and chemical reactions, and the reaction pathway of the ring transformation are described.Keywords - pyrimidine N-oxide; diketene; ring transformation; oxazolopyridine; isoxazolopyridine
