PRODUCT INTRODUCTION
description
Dimethyl maleate is a maleate ester resulting from the formal condensation of both carboxy groups of maleic acid with methanol. It is commonly used as a dienophile for Diels-Alder-type cycloaddition reactions in organic synthesis. It is a maleate ester, a diester and a methyl ester. It is functionally related to a methanol.
