The alkylation of 4-alkoxymethyl-2-ethoxycarbonylbutanolides led to the formation of 2-alkenyl-4-alkoxymethyl-2-ethoxycarbonylbutanolides which at alkaline hydrolysis provided new 2-alkenyl-4-alkoxymethylbutanolides. By oxidation of the latter with a mixture of hydrogen peroxide and formic acid 4-alkoxymethyl-2-(2-R-2,3-dihydroxy)propylbutanolides were obtained. The diololactones were shown to suffer under the conditions of the pinacol-pinacolone rearrangement a conversion into previously unknown formyl- and epoxylactones.
