METHOD FOR PREPARING AN AMINO ACID FROM 2-AMINOBUTYROLACTONE

摘要

The invention relates to a method for preparing an amino acid, or the salts thereof, from 2-aminobutyrolactone (2ABL), wherein said amino acid has formula I, XCH2CH2CHNH2COOH, where X is a nucleophilic ion and, wherein according to the method, the 2-aminobutyrolactone (2ABL) is N-carboxylated by means of carbon dioxide, and the resulting 2ABL carbamate is reacted with an XH reagent or the salts thereof.
