- Preparation method of chiral alpha-amino acid
-
The invention discloses a preparation method of chiral alpha-amino acid. Initial raw materials comprising aldehyde and N-acryl substituted glycine undergo Erlenmeyer-Plochl cyclization, hydrolysis or alcoholysis, asymmetric catalytic hydrogenation and acid hydrolysis to obtain the chiral alpha-amino acid compound. The method adopting the above synthesis route has the advantages of mild reaction conditions, simple technological operation, safe and stable production, realization of high yield, good chemical purity and good optical purity of the above obtained product, wide application range, and suitableness for industrial production.
