Amino nitrile intermediate for the preparation of alanine diacetic acid |
摘要 |
A novel intermediate useful in the synthesis of alpha-alanine diacetic acid or its salts is disclosed. The intermediate can be formed by contacting alanine with glycolonitrile under alkaline conditions or glycine with lactonitrile to form an aminonitrile which can be hydrolyzed and then contacted with additional glycolonitrile to form the nitrile intermediate which can be converted to alpha-alanine diacetic acid via hydrolysis.
