The esters are hydrolyzed in aqueous media, under acid or base catalysis, to yield carboxylic acids and alcohols. Basic hydrolysis is called saponification and transforms esters into carboxylates.

Lactones are cyclic esters and hydrolyze in a manner analogous to noncyclic esters, forming compounds containing acid and alcohol groups.

Esters react with alcohols in acidic media, replacing their alkoxy group with the corresponding alcohol, as can be seen in the following reaction. This reaction is called transesterification.

The esters have acidic hydrogens with pKa=25 in their position, which can be subtracted using bases. The conjugate base is an enolate ester, a highly nucleophilic species that attacks a varied number of electrophiles.

When an ester with hydrogens a is treated with an equivalent of base (alkoxide) it condenses to form a product of the family of 3-ketoesters. This type of reaction is known as a Claisen condensation.
