In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride, molecular formula is C14H22ClNO9. In a Article，once mentioned of 10034-20-5, Application In Synthesis of (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride
The reactions of 2-amino- and 2-alkylamino-2-deoxyglycopyranoses with isothiocyanates gave thioureas and heterocyclic derivatives. Moreover, cis- fused glycopyrano[2,1-d]imidazolidin-2-thiones, which have a close structural analogy with some naturally-occurring glycosidase inhibitors, were synthesised for the first time. The mechanism of formation of glycofurano and glycopyrano[2,1-d]imidazolidin-2-thiones occurs via the intermediacy of monocyclic 5-hydroxyimidazolidin-2-thiones. These substances are generated by intramolecular nucleophilic addition of an NH group to the aldehyde function of the sugar. The monocyclic intermediates have been isolated and their participation in the formation of bicyclic imidazolidin-2-thiones and/or monocyclic imidazolin-2-thiones proved. In stark contrast, cis-fused glycopyranothiazolidines were prepared by nucleophilic displacements.
