A practical, facile method was developed for the preparation of 1,5-anhydroalditol via per-O-TMS-glycopyranosyl iodide with LiBH4. A series of 1,5-anhydroalditols were prepared in excellent yields (up to 92%) from unprotected carbohydrates within 2 days under mild conditions. In addition, multi-gram scale preparation of 1,5-anhydroglucitol (1,5-AG), a major polyol present in human serum, was developed
开发了一种实用的,简便的方法,可通过过O -TMS-甘露糖基碘碘化物与LiBH 4制备1,5-脱水醛糖醇。在温和条件下,在2天内从未保护的碳水化合物中以极高的收率(高达92%)制备了一系列1,5-脱水醛糖醇。此外,使用相同的程序开发了克级制备的1,5-脱水葡萄糖醇(1,5-AG)(一种存在于人血清中的主要多元醇),而无需进行色谱纯化。
