The total synthesis of methyl 3,6-dideoxy-4- C -( d - altro -1,3,4,5 tetrahydroxyhexyl)-α- d - xylo -hexopyranoside, the methyl glycoside of the recently isolated 4- C -branched sugar caryophyllose, has been completed in a stereoselective and convergent manner. The synthesis of this dodecose relies on the diiodosamarium mediated coupling of two six-carbon fragments: a cyclic ketone and an acid chloride
摘要3,6-二脱氧-4-C-(d-atro -1,3,4,5四羟基己基)-α-d-木基-己吡喃糖苷(最近分离出的4-C-的甲基糖苷)的总合成支链糖核果糖,已经以立体选择性和会聚的方式完成。该十二糖的合成依赖于二碘osa介导的两个六碳片段的偶联:环状酮和酰氯。
