Mild Deprotection of Methyl, Benzyl, Methoxymethyl, Methylthiomethyl, Methoxyethoxymethyl, andβ-(Trimethylsilyl)-ethoxymethyl Esters with AlCl3-N,N-dimethylaniline

Abstract
Methyl, benzyl, methoxymethyl, methylthiomethyl, methoxyethoxymethyl, and β-(trimethylsilyl)ethoxymethyl esters could be cleaved readily under mild conditions on treatment with AlCl3-N,N-dimethylaniline in CH2Cl2 to give parent carboxylic acids in high yields.
