摘要：

The peracid oxidation of methyl 2-(t-butyldimethylsilyloxy)-2-alkenoates 2 furnished the corresponding epoxides 3 in good yields. The regiospecific opening of the latter compounds with methanol afforded 3-hydroxy 2-acetal-esters 4. When alkyl disubstituted in position 3, compounds 3 or 4 could be deprotected to give rise to 3-hydroxy 2-keto-esters 5.
