  Triazole carboxylic acids as anionic sugar mimics? Inhibition of glycogen phosphorylase by a d-glucotriazole carboxylate

  摘要：

  Triazole-carboxylic acids related to D-glucose and D-galactose may be prepared by intramolecular [1,3]-dipolar cycloadditions of azides to unsaturated esters, followed by bromine oxidation of the resulting triazoline. Such materials may provide a series of anionic mimics of carbohydrates. (C) 1997 Elsevier Science Ltd.
