Title:
METHOD FOR PRODUCING N-ALKYL AMINO ACID AND PEPTIDE INCLUDING N-ALKYL AMINO ACID
Document Type and Number:
WIPO Patent Application WO/2023/127869
Kind Code:
A1
Abstract:
The present invention pertains to a method for producing a N-monoalkyl amino acid or an ester thereof, or a peptide including the N-monoalkyl amino acid or an ester thereof, the method comprising an alkylating step for mixing, in the presence of hydrogen and in a solvent: a starting amino acid or an ester thereof, or a peptide including the starting amino acid or an ester thereof; a C1-C6 primary alkylating agent or a substituted methyl halide; and a catalyst. The alkylating step is performed at a pressure of 1 atm or more, and is for generating a N-monoalkyl amino acid or an ester thereof, or a peptide including the N-monoalkyl amino acid or an ester thereof, obtained by binding a primary alkyl group corresponding to the C1-C6 primary alkylating agent or a substituted methyl halide with respect to the starting amino acid or an amino group of an ester thereof.
