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.
