Several new chiral synthons based on the 4-amino-1,2,4-triazole moiety have been prepared by the condensation reaction of opticallyactive α-hydroxy- and α-aminoacids with hydrazine. A general method for the determination of the optical purity of chiral 4-amino-3,5-disubstituted-1,2,4-triazoles based on their oxidation with lead tetraacetate (LTA) is described.
