The Efficient Synthesis of Alkoxy-esters from Hydroxy Carboxylic Acids Using Dimsyllithium in Dimethylsulfoxide Followed by Alkylation with an Alkyl Halide

Hydroxy acids are converted directly into the related alkyl ether-alkyl esters in high yields in a single operation by double deprotonation using dimsyllithium in dimethylsulfoxide followed by treatment with an alkyl halide.
