lactopyranosyl) dithiocarbonates have been easily prepared via a two-step azidoxanthation reaction of the corresponding galactals (1,5-anhydro-2-deoxy-D-lyxo-hex-1-enitols).They are efficient glycosyl donors for the stereoselective synthesis of protected precursors of biologically important galactosamine-containing oligosaccharides.
通过相应半乳糖(1,5-脱水-2-脱氧-D- lyxo)的两步叠氮蒽并化反应,可以轻松制备各种取代的O-乙基S-(2-叠氮基-2-脱氧-D-吡喃半乳糖基)二硫代碳酸酯。(-hex-1-enitols)。它们是有效的糖基供体,用于立体选择性地合成具有生物学重要性的含半乳糖胺的寡糖的保护前体。
