The cis-dihydrodiol metabolite from methyl benzoate has been used as a synthetic precursor of carba-β-L-galactopyranose, carba-β-L-talopyranose and carba-α-L-talopyranose. The structures and absolute configurations of these carbasugars were determined by a combination of NMR spectroscopy, stereochemical correlation and X-ray crystallography.
苯甲酸甲酯的顺式二氢二醇代谢物被用作carba-δ²-L-吡喃半乳糖、carba-δ²-L-吡喃谷糖和carba-δ±-L-吡喃谷糖的合成前体。这些碳糖的结构和绝对构型是通过核磁共振光谱、立体化学相关性和 X 射线晶体学相结合的方法确定的。
