Abstract
Methylthiomethyl esters of α,β-unsaturated acids 2were converted into the corresponding ketene acetals 3by O-silylation. Ketene acetals rearranged in refluxing toluene to give, after methanolysis, the corresponding γ-methylthiomethyl substituted methyl esters 4. In the case of phenylthiomethylesters the products of α-substitution were observed.
