The synthesis of five different 5,6-dideoxyhex-5-enofuranosides (5, 7, 9 and 11) proceeds in 30–60% overall yield in two steps from commercially available 1-0-methyl pyranosides by reductive β-elimination of the intermediate 6-bromo-6-deoxypyranosides.
通过还原性的β-消除作用,从市售的1-0-甲基吡喃糖苷中分两步合成了5种不同的5,6-二脱氧己基-5-烯呋喃糖苷(5、7、9和11),总产率为30-60%。中间体6-溴-6-脱氧吡喃糖苷。
