General description

D-(+)-Glucuronic acid γ-lactone (Glucourono-γ-lactone, Glucurone or Glycurone) is a carbohydrate derivative. It converted into L-ascorbic acid in animals and human body. Its molecule contains two five-membered rings. Its crystal structure has been studied.

Application

D-(+)-Glucuronic acid γ-lactone may be used in the following studies:
  • As starting ragent in the synthesis of 2,3,4,-tris(tert.-butyldimethysilyl) glucuronic acid trichloroethylester, required for the preparation of 1-O-acyl glucuronide of the anti-inflammatory drug ML-3000.
  • Synthesis of optically active glucopyranoses.
  • Synthesis of long-chain alkyl glucofuranosides.
