Acid hydrolysis of 6-deoxy-1,2-O-isop ropylidene-α-d-xylo-hexo-furanos-5-ulose (4) yielded gummy 6-deoxy-d-xylo-hexos-5-ulose (1) as an isomeric mixture of two furanose forms, 6-deoxy-α-d-xylo-hexo-furanos-5-ulose and 6-deoxy-β-d-xylo-hexofuranos-5-ulose, and a pyranose structure 1R, 5R-6-deoxy-d-xylo-hexopyranos-5-ulose. The combined percentage (64%) of the furanoses represents an unusually large amount of free carbonyl form for a sugar when compared to simple hexoses and 2-hexuloses. Isomeric structures were determined in deuterium oxide solution by 1H and 13C NMR. |
