A method of preparing a ribofuranose derivative essentially free of pyranose compounds includes a step of contacting a solution of MDR containing MDRP as an impurity in a solvent including methanol and/or tetrahydrofuran with at least one alkali metal periodate under conditions sufficient to oxidize at least a portion of the MDRP. MDR containing at most 5 wt% of MDRP based on the total weight of MDR and MDRP may be produced.

An efficient synthesis of 2-deoxy-L-ribose was achieved without chromatography starting from its enantiomer 2-deoxy-D-ribose in more than 30% overall yield. An unexpected product, 2-deoxy-xylose, was obtained under slightly different reaction conditions and isolated with partial racemization. The structure of the scalemic 2-deoxy-xylose was confirmed by X-ray crystallography.
2-脱氧-L-核糖的有效合成是从其对映异构体2-脱氧-D-核糖开始的,无需色谱法,总产率超过30%。在稍微不同的反应条件下获得了意想不到的产物 2-脱氧木糖,并通过部分外消旋化进行分离。比例尺 2-脱氧木糖的结构由 X 射线晶体学证实。
