practical process for the preparation of anhydroalditols from commodity carbohydrates has been described. Reductive cleavage of the glycosidic linkage in perallylated carbohydrates with triethylsilane gave the protected anhydroalditols, which were then deallylated using a PdCl2-CuCl2-Activated Charcoal system. Valuable anhydroalditols, such as 1,5-anhydro-D-glucitol, 1,5-anhydro-D-mannitol, 2,5-anhydro-D-glucitol
已经描述了从商品碳水化合物制备脱水醛糖醇的实际方法。用三乙基硅烷还原高丙基化碳水化合物中糖苷键,得到被保护的脱水醛糖醇,然后使用PdCl 2 -CuCl 2活化木炭系统将其脱羧。有价值的脱水醛糖醇,例如1,5-脱水-D-葡萄糖醇,1,5-脱水-D-甘露糖醇,2,5-脱水-D-葡萄糖醇,2,5-脱水-D-甘露糖醇和1,4-脱水-右旋糖醇是从碳水化合物,例如葡萄糖,甘露糖,核糖,蔗糖,纤维素,淀粉和左旋糖中高产率和高纯度制备的。
