X-RAY STRUCTURES OF A 3-AMINO-5-SUBSTITUTED 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-erythro-hexo-2-ulose ("3-deoxyglucosone"), a Maillard reaction intermediate, gives two triazines, 3-amino-5-([2S],[3S]-2,3,4-trihydroxybutyl)-1,2,4-triazine (1) and 3-amino-6-([2S],[3S]-2,3,4-trihydroxybutyl)-1,2,4-triazine (2) which have been obtained in the crystalline state. The structure of the triazines, as determined by X-ray diffraction, are reported herein.
