d-Glucuronic acid glycals can be efficiently synthesized from diacetone glucose or tri-O-acetyl glycal and can be transformed into d-glucuronic acid donors and acceptors in high yields. Base catalyzed epimerization of d-glucuronic acid glycals provides access to the corresponding l-iduronic acid glycals. Both d-glucuronic and l-iduronic acid glycals were transformed into glycosylating agents for use
d-葡糖醛酸糖可以由双丙酮葡萄糖或三-O-乙酰基糖有效地合成,并且可以高产率转化为d-葡糖醛酸的供体和受体。d-葡萄糖醛酸糖基的碱催化的差向异构体提供了进入相应的l-艾杜糖醛酸糖基的途径。d-葡萄糖醛酸和l-艾杜糖醛酸的糖都被转化为糖基化剂,用于合成糖胺聚糖寡糖。
