摘要： 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.

摘要： 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 ruthenium metal or a ruthenium compound. Preferably, the step is carried out under pressurized condition, and more preferably, in the presence of at least one typical metal selected from the group consisting of an alkali metal compound and an alkaline earth metal compound.
