Abstract

PURPOSE:To obtain the titled compound useful as an intermediate for drugs by simple operation in high yield, by reacting fumaric acid with hydrogen peroxide in an alkali aqueous solution in the presence of a catalyst and treating the reaction product with a strongly acidic ion exchange resin without isolating the reaction product. CONSTITUTION:Fumaric acid is treated with hydrogen peroxide in an alkali aqueous solution in the presence of a small amount of a catalyst (e.g. disodium tungstate dihydrate). Prepared D,L-trans epoxysuccinic acid alkali salt, without isolation, is treated with a strongly acidic ion exchange resin to give the aimed compound. The amount of the catalyst used is preferably 0.05-1.0 equivalent based on the acid.
