X-Ray Structures of a 3-Amino-5- and a 3-Amino-6-Substituted Triazine, Produced as a Result of a Reaction of 3-Deoxy-D-Erythro-Hexos-2-Ulose (3-Deoxyglucosone) with Aminoguanidine

Aminoguanidine is a potent inhibitor of color formation during the Maillard reaction. The reaction of aminoguanidine with 3-deoxy-D-erytho-hexo-2-ulose (“3-deoxyglucosone”), a Maillard reaction intermediate, gives two triazines, 3-amino-5-([2S],[3S]-2,3,4-trihydroxybutyl)-l,2,4-triazine (1) and 3-amino-6-([2S],[3S]-2,3,4-trihydroxybutyl)-l,2,4-triazine (2) which have been obtained in the crystalline state. The structure of the triazines, as determined by X-ray diffraction, are reported herein.
