Chemistry of non-enzymic browning. V. The preparation of Aldose-Potassium bisulphite addition compounds and some amine derivatives

Abstract

From the reaction of potassium bisulphite with D-glucose the glucose-potassium bisulphite addition compound, D-glycero-D-ido-1,2,3,4,5,6-hexahydroxyhexyl potassium sulphonate was prepared pure and crystalline. Similar new compounds were prepared from the reaction of potassium bisulphite with D-galactose, L-rhamnose, D-mannose, and L-arabinose. The reaction of the glucose-potassium bisulphite addition compound with aniline, gave pure crystalline D-glycero-D-ido-1-anilino-2,3,4,5,6-pentahydroxyhexyl potassium sulphonate. Similar derivatives were prepared from p-toluidine, p-anisidine, and o-phenylenediamine. The aniline and p-toluidine derivatives were also prepared from the glucose-sodium bisulphite addition compound.
