Abstract

Trifluoromethanesulfonic acid-coated silica in the absence of solvents is an effective reagent for hydrolysis of sterically crowded chiral esters giving chiral acids in good chemical and optical yield. On the other hand, the method was unsuitable for the separation of optically pure alcohols from chiral esters because dehydration usually takes place during the reaction course.
