D-Altronic acid

A chiral p-polyamide 83 of the Nylon 3 type was also synthesized [68, 69] by Galbis et al. by ring-opening polymerization of the p-lactam derived from 3-amino-3-deoxy-2,4,5,6-tetra-(9-methyl-D-altronic acid. [Pg.163]

Improvements in the Ruff degradation40 made by Hockett and Hudson34 have been applied by Hudson and Richtmyer41 to the preparation of D-ribose from the calcium salt of D-altronic acid (IX) the latter may be obtained from sedoheptulose, lactose, cellobiose and D-glucose.4... [Pg.140]

Isolation of the same product from d-dextro-ribohexosaminic acid and d-dextro-lyxohexosaminic acid indicates that the common product must be 2,5-anhydro-n-talaric acid (LXIIIa) which is the same as 2,5-anhydro-D-altraric acid (LXIIIb) and is derived from the oxidation both of 2,5-anhydro-D-altronic acid (LXXXVII) and of 2,5-anhydro-D-talonic acid... [Pg.54]

The structure of celtrobiose was established through its oxidation to celtrobionic acid and subsequent cleavage with N sulfuric acid to n-glucose and D-altronic acid. Since the biose linkage should not be affected by the aluminum chloride rearrangement, celtrobiose was thus proved to be 4-/3-D-glucopyranosido-n-altrose. [Pg.44]

Draw the product of a Ruff degradation of d-altronic acid. [Pg.1446]

The sugar has been suggested as a source for D-altrose and D-ribose since it is easily oxidized by oxygen in alkaline solution to D-altronic acid calcium D-altronate is oxidized by hydrogen peroxide and ferric acetate to D-ribose. These reactions also provide proof for the assignment of the D-altrose configuration to the sugar (122). [Pg.102]
