Phosphorylation of D-glucose derivatives with inorganic cyclo-triphosphate: substituent effect at the 5-CH2OH or 2-OH group.
The phosphorylation of several D-glucose derivatives has been achieved using inorganic sodium cyclo-triphosphate hexahydrate (P3m), Na3P3O9 x 6H2O, in aqueous solution. In the phosphorylation of D-glucuronic acid, 6-phosphoryl-D-glucose and D-xylose, beta-D-glucuronic acid 1-triphosphate, 6-phosphoryl-beta-D-glucose 1-triphosphate and beta-D-xylose 1-triphosphate were synthesized stereoselectively with maximum yields of 43.5, 32.8 and 41.9%, respectively. In the case of D-glucosamine and 2-deoxy-D-glucose, the main phosphorylated products were assigned to beta-D-glucosamine 1-triphosphate and 2-deoxy-beta-D-glucose 1-triphosphate by 1H-, 13C- and 31P-NMR, and the yields were 13.9 and 13.4%, respectively.
