Starting from 1,2:5,6-di-O-isopropylidene-β-D-altrofuranose, 5,6-dideoxy-1,2-O-isopropylidene-5-[(methoxy)phenylphosphiny1]-3-O-methyl-β-D-arabino-hexofuranose was prepared in a 6 step sequence (13% overall yield). It was converted into the title compounds, which were characterized as the 1,2,4-triacetates.
从 1,2:5,6-di-O-isopropylidene-β-D-altrofuranose, 5,6-dideoxy-1,2-O-isopropylidene-5-[(甲氧基)phenylphosphiny1]-3-O-methyl 开始-β-D-阿拉伯-己基呋喃糖按 6 步顺序制备(总产率为 13%)。将其转化为标题化合物,其表征为 1,2,4-三乙酸酯。
