Meso-succinates, readily available by Diels-Alder cycloaddition of dimethyl maleate or maleic anhydride followed by esterification, can be isomerized quantitatively from the cis to the trans isomers in the presence of lithium alkoxides. The reaction performed with enantiopure chiral lithium alkoxides yields diastereomeric trans-succinates in good yield and selectivity. (C) 1999 Elsevier Science Ltd. All rights reserved.
