Treatment of methyl 5-deoxy-5-C-( diethoxyphosphinyl )-2,3-O-isopropylidene-beta-D- ri bofuranoside with sodium dihydrobis (2- methoxyethoxy ) aluminate , followed by hydrogen peroxide, mineral acid, and hydrogen peroxide, gave 5-deoxy-5-C-( hydroxyphosphinyl )-alpha,beta-D- ribopyranoses in 40-45% overall yield. The structures of these sugar analogs were effectively established on the basis of the
用二氢双(2-甲氧基乙氧基)铝酸钠,然后用过氧化氢,无机酸和过氧化氢处理5-脱氧-5-C-(二乙氧基膦基)-2,3-O-异亚丙基-β-D-呋喃呋喃糖苷得到总产率为40-45%的5-脱氧-5-C-(羟基膦基)-α,β-D-核糖吡喃糖。这些糖类似物的结构是根据标题化合物的质量和400 MHz,1H-nmr光谱有效地建立的,该标题化合物是先用重氮甲烷,然后用乙酸酐在吡啶中处理的。
