4-ETHOXYMETHYLENE-2-PHENYL-5(4H)-OXAZOLONE AS A SYNTHON FOR THE SYNTHESIS OF SOME 2H-PYRAN-2-ONES

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.
