| titleOfInvention | Process for producing α-L-aspartyl-D-amino acid-N- (S) -α-alkylbenzylamide |
| abstract | (57) [Summary] (Modified) [Purpose] α-L-aspartyl-D-amino acid-N- A method for producing (S) -α-alkylbenzylamide is provided. [Structure] Strong acid addition salt of L-aspartic anhydride and D -Amino acid-N- (S) -α-alkylbenzylamide is condensed to give α-of the general formula 1 with good reaction selectivity and high yield. L-Aspartyl-D-amino acid-N- (S) -α-alkylbenzylamide is obtained. Further, the reaction solution was made alkaline, and the excess D-amino acid-N- (S) -α-alkylbenzylamide was extracted and removed in an organic solvent, and the aqueous layer was adjusted to pH 4.5 to 6.5 for crystallization. Α-as crystals L-Aspartyl-D-amino acid-N- (S) -α-alkylbenzylamide is obtained. (R 1 represents a C1-4 alkyl group, and R 2 represents a C1-3 alkyl group.) |
