Abstract
The present invention relates to a method for producing a specified α-amino acid, the method including allowing a specified α-amino acid amide and water to react with each other in the presence of a zirconium compound which contains zirconium and at least one metal element selected from the group consisting of lithium, nickel, copper, zinc, cesium, barium, hafnium, tantalum, cerium, and dysprosium.
Claims10
A method for producing an α-amino acid represented by the following general formula (2), comprising allowing an α-amino acid amide represented by the following general formula (1) and water to react with each other in the presence of a zirconium compound which contains zirconium and at least one metal element selected from the group consisting of lithium, nickel, copper, zinc, cesium, barium, hafnium, tantalum, cerium, and dysprosium:
- wherein
- in the general formulae (1) and (2), R1 is a hydrogen atom, an optionally substituted alkyl group having 1 to 6 carbon atoms, an optionally substituted cycloalkyl group having 3 to 6 carbon atoms, an optionally substituted aryl group having a ring-constituting carbon number of 6 to 10, or an optionally substituted heteroaryl group having a ring-constituting atom number of 4 to 13.
