NEW MATERIAL:A compound expressed by formula I (R<1>-R<3> are H or acetyl). EXAMPLE:(S)-(-)-14-Hydroxy-15-aminomethyl-2, 8-dithia[9](2, 5)pyridinophaneS, S, S', S'-tetraoxide. USE:A synthetic reagent for optically active amino acids. PREPARATION:A compound expressed by formula II, e.g. (S)-(-)-15- aminomethyl-14-hydroxy-2, 8-dithia[9](2, 5)pyridin-ophane, is reacted with an acylating agent, e.g. acetic anhydride/pyridine, to give a novel compound expressed by formula III, which is then treated with an oxidizing agent, e.g. hydrogen peroxide and, as necessary, deacetylated. When the hydrogen peroxide is used, the reaction is carried out in the presence of a mixed solvent of dioxane and water and a catalyst, e.g. sodium tungstate-acetic acid.
