Synthesis of 2-alkyl amino acids

摘要

A method of preparing a 2-alkyl amino acid involves the aziridination of an alkylacrylate and the opening of the aziridine ring by addition of a side chain. This method can result in the preparation of enantiomeric excess of a 2-alkyl amino acid. The invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.
