6-Di-O-benzyl-5-deoxy-5-dimethylphosphinyl-1,2-O-isopropylidene-α-D-glucofuranose 5 was converted, in four steps, into methyl 2-acetamido-3,6-di-O-benzyl-2,5-dideoxy-5-dimethoxyphosphinyl-α-D-mannofuranoside 7, which led to 3,5-di-O-benzyl derivatives 9 of a P-in-the-ring D-mannosamine analogue.
3,6-二-O-苄基-5-脱氧-5-二甲基亚膦酰基-1,2 - O-异亚丙基-α- D-葡萄糖呋喃糖5经四个步骤转化为2-乙酰氨基-3,6-di - ø -苄基-2,5-二脱氧-5-二甲氧基氧-α- d -mannofuranoside 7,这导致了3,5-二- ø -苄基衍生物9的P内式环的d -mannosamine类似物。
