The present invention provides a novel process for preparing a sulfur-containing 2-ketocarboxylate compound without using any enzyme. The process comprises a step of oxidizing a hydroxyacetate compound having an optionally-substituted sulfur-containing hydrocarbon group at 2-position in the presence of a vanadium compound. Preferably, the step is carried out further in the presence of oxygen, and more preferably, in the presence of an organic solvent.
本发明提供了一种新型的制备含硫2-酮羧酸酯化合物的方法,不需要使用任何酶。该方法包括在钒化合物存在的情况下氧化2-位置具有可选取代硫代烃基的羟基乙酸化合物的步骤。最好在氧气存在的情况下进行该步骤,更好的是在有机溶剂存在的情况下进行。
