Two rare sugars – 1-deoxy-L-fructose and L-sorbose – were synthesized from inexpensive starting materials by a carbonyl translocation method developed in our laboratory. Reduction of a known starting compound gave a 1,5-diol derivative. Selective protection of the corresponding primary alcohol and oxidation of the secondary alcohol provided the desired product in acyclic, protected form. Subsequent
两种稀有糖——1-脱氧-L-果糖和L-山梨糖——是通过我们实验室开发的羰基易位方法从廉价的起始材料合成的。已知起始化合物的还原得到1,5-二醇衍生物。相应伯醇的选择性保护和仲醇的氧化提供了无环、受保护形式的所需产物。随后的脱保护导致从已知原料分五个步骤生产 1-脱氧-L-果糖,总产率为 42%。这种方法代表了 1-脱氧-L-果糖的化学合成的第一份报告。应用类似的策略将廉价的 D-葡萄糖转化为 L-山梨糖,L-山梨糖由已知起始材料分五步制备,总产率为 55%。
