Treatment of 4-ethoxymethylene-2-phenyl-5(4H)-oxazolone with activated methylene compounds under acidic or basic conditions leads to 2H-pyran-2-ones and fused pyran-2-ones.On the other hand, methyl (3-benzoylamino-5-methoxycarbonyl-2-oxo-2H-pyran-6-yl)acetate (4) has also been prepared by a one-pot synthesis from dimethyl 1,3-acetone dicarboxylate, diethoxymethyl acetate, hippuric acid and acetic anhydride.

A general one-pot synthesis of some 2H-pyran-2-ones and fused pyran-2-ones starting from 1,3-dlcarbonyl compounds, N-acylglycines and one-carbon synthons (trialkyl orthoformates, diethoxymethyl acetate or N,N-dlmethylformamide dimethyl acetal) in acetic anhydride (or in a mixture of acetic anhydride and acetic acid) is described.
