N,N-diarylammonium pyrosulfate efficiently catalyzes the hydrolysis of esters under organic solvent-free conditions. This reverse micelle-type method is successfully applied to the hydrolysis of various esters without the decomposition of base-sensitive moieties and without any loss of optical purity for α-heterosubstituted carboxylic acids.
