  A process for preparing a malonic acid monoester or &bgr;-ketoester from an epoxide includes the steps of reacting an epoxide with carbon monoxide and an alcohol in the presence of a catalytic amount of a cobalt compound and at least one promoter to produce a &bgr;-hydroxyester, separating the &bgr;-hydroxyester from the cobalt compound and the promoter, and oxidizing the &bgr;-hydroxyester to produce a malonic acid monoester or &bgr;-ketoester.

  从环氧化物制备丙二酸单酯或β-酮酯的过程包括以下步骤：在钴化合物的催化作用下，将环氧化物与一氧化碳和醇反应，并加入至少一种促进剂以产生β-羟基酯，将β-羟基酯与钴化合物和促进剂分离，然后氧化β-羟基酯以产生丙二酸单酯或β-酮酯。

  The present invention relates to a particularly economic overall method for producing menthol, specifically for producing optically active, essentially enantiomerically and diastereomerically pure L-menthol and racemic menthol, starting from the starting material citral which is available inexpensively on an industrial scale. The method comprises the following steps a.1) catalytic hydrogenation of neral and/or geranial to give citronellal, b.1) cyclization of citronellal to isopulegol in the presence of an acidic catalyst, c.1) purification of isopulegol by crystallization and d.1) catalytic hydrogenation of isopulegol to give menthol.
