METHOD FOR PRODUCING N-ACYLATED beta-AMINO ACID HAVING CONCENTRATED ENANTIOMER, METHOD FOR PRODUCING beta-AMINO ACID BY PROTECTIVE GROUP SEPARATION AND USE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for a -amino acid production, which is excellently usable on an industrial scale, eventually, economically excellent, for example, excellent from the viewpoint of ecology, with which a -amino acid is produced under low hydrogen pressure in a shorter hydrogenation time. SOLUTION: An N-acylated 5-amino acid having concentrated enantiomer is obtained by carrying out an enantiomer-selective catalytic hydrogenation of a prochiral N-acylated Z-5-aminoacrylic acid in the presence of a compound represented by general formula (I) [R1 , R2 , R3 and R4 are each described in the specification] in a polar solvent.
