摘要: The present invention relates to a process for the in situ preparation of optically pure (S)-3,4-dihydroxybutyric acid derivatives represented by Formula [2] and more particularly, which enables preparing (S)-3-hydroxy-γ-butyrolactone [1] oxidation α- or β-(1,4) linked disaccharide oligosaccharide with an oxidant under basic condition give cyclization sequentially acidic (S)-3-hydroxy-γ-butyrolactone.
