Abstract
The invention relates to a method for preparing an amino acid, or its salts, from 2-aminobutyrolactone (2ABL), said amino acid fitting the formula I, XCHCHCHNHCOOH, wherein X is such that Xrepresents a nucleophilic ion, according to which N-carboxylation of 2-aminobutyrolactone (2ABL) is achieved with carbon dioxide, and the thereby obtained 2ABL carbamate is reactive with an XH reagent or its salts.
