Preparation method of racemic ketoisoleucine calcium and intermediate thereof

The invention relates to a preparation method of racemic ketoisoleucine calcium and an intermediate thereof, the method comprises the following steps: reacting hydantoin and butanone in ammonia water to obtain sec-butyl hydantoin, adding strong base for reaction, and obtaining racemic ketoisoleucine salt with high yield and high purity without complex post-treatment steps. Calcium racemization ketoisoleucine can be prepared by using the calcium racemization ketoisoleucine salt prepared by the method, high-yield and high-purity calcium racemization ketoisoleucine can be obtained, the reaction solvent can be recycled and reused, the method is green and environment-friendly, and the problem of pollution to the environment is solved.
