Preparation of three positional isomers of diglucosyl-cyclomaltohexaose
Three positional isomers of diglucosyl-cyclomaltohexaose (diglucosyl-cG6) were chemically synthesized via 61,62-, 61,63-, and 61,64-di-O-(tert-butyldimethylsilyl)-cG6s (1, 2, and 3) prepared regiospecifically. Glucosylation of bis(2,3-di-O-acetyl)tetrakis(2,3,6-tri-O-acetyl)-cG6s obtained from the three regioisomeric compounds 1, 2, and 3 with 2,3,4,6-tetra-O-benzyl-1-O-trichloroacetimidoyl-alpha-D-glucopyranose, followed by debenzylation and then deacetylation, afforded 61,62-, 61,63-, and 61,64-di-O-(alpha-D-glucopyranosyl)-cG6s (10, 11, and 12) together with configurational isomers. The desired compounds 10, 11, and 12 containing two (1 ? 6)-alpha-linkages were isolated from the mixtures of their configurational isomers by high performance liquid chromatography. The three diglucosyl-cG6s synthesized chemically were used as authentic samples to identify the components in a mixture of diglucosyl-cG6s produced by an enzymatic process.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 74808-09-6 is helpful to your research., Reference of 74808-09-6
