nearly neutral pH into 1,2:5,6-dianhydrogalactitol ( 4 ), 1,2-anhydro- D -mannitol ( 6 ), and 2,3:4,5-dianhydro- D -iditol ( 9 ). Strongly alkaline conditions yielded 2,3:4,5-dianhydro- L -iditol ( 7 ) from 1,6-di- O -methanesulphonyl- D -mannitol ( 1 ). The structures of compounds 4, 6, 7, and 9 were confirmed by p.m.r. spectroscopy, and by their reactivity towards thiosulphate and iodide ions. The conversion
摘要将1,6-二溴-1,6-二脱氧半乳糖醇(2),1-O-甲磺酰基-D-甘露醇(5)和3,4-二-O-甲磺酰基-D-甘露醇(8)分别转化为接近中性的pH值进入1,2:5,6-二脱水半乳糖醇(4),1,2-脱水D-甘露糖醇(6)和2,3:4,5-二脱水D-ID糖醇(9)。强碱性条件由1,6-二-O-甲磺酰基-D-甘露糖醇(1)产生2,3:4,5-二脱水-L-ID醇(7)。化合物4、6、7和9的结构通过pmr光谱及其对硫代硫酸根和碘离子的反应性得到了证实。1,2:5,6-二脱水-D-甘露醇(3)转化为1,6-二脱氧-1,6-二碘-D-甘露醇,1,6-二溴-1,6-二脱氧-D-描述了甘露糖醇和1,6-二-O-苯甲酰基-D-甘露糖醇和1,2:5,6-二脱水半乳糖醇成1,6-二脱氧-1,6-二碘代半乳糖醇。
