Abstract 2-Deoxy- d - arabino -hexitol ( 6 ) was obtained by borohydride reduction of 2-deoxy- d - arabino -hexose ( 5 ). The synthesis of 5 , starting from 2,3:4,5-di- O -isopropylidene- d -arabinitol ( 1 ), was achieved by a one-carbon chain-elongation involving formylation of the Grignard reagent derived from 1-bromo-1-deoxy-2,3:4,5-di- O -isopropylidene- d -arabinitol ( 2 ), using lithium formate
摘要通过硼氢化物还原2-脱氧-d-阿拉伯糖基己糖(5)获得了2-脱氧-d-阿拉伯糖基己糖醇(6)。由2,3:4,5-二-O-异亚丙基-d-阿拉伯糖醇(1)开始的5的合成是通过一个碳链延长而实现的,该加长涉及衍生自1-bromo-使用甲酸锂,将1-脱氧-2,3:4,5-二-O-异亚丙基-d-阿拉伯糖醇(2),然后水解除去异亚丙基。固定化的氧化葡糖杆菌细胞(ATCC 15178)选择性氧化6生成5-脱氧-d-苏-己糖(7),产率为65%(总产率为1的9%)。
