    Absolute Stereostructures of Spinacosides C and D with a Novel Acetal Type Substituent from Spinacia oleracea (Spinach) and Basella rubra (Indian Spinach)
    摘要:
    Spinacosides C and D with a novel acetal-type substituent were isolated from the fresh aerial parts of Spinacia oleracea (Spinach) and Basella rubra (Indian spinach). Their absolute stereostructures were determined on the basis of physicochemical and chemical evidence, which included the conversion from the alpha-L-arabinopyranosyl moiety of a known saponin momordin I to the acetal-type substituent of spinacoside D.

    pentasaccharide based on the heparin antithrombin-binding domain. In the frame of our ongoing research aimed at the synthesis of sulfonic acid-containing heparinoid anticoagulants, we elaborated a modular pathway to obtain a series of idraparinux-analogue pentasaccharides bearing one or two primary sulfonic acid moieties. Five protected pentasaccharides with different C-sulfonation patterns were prepared by two subsequent
