Abstract Several nucleophiles were separately treated with methyl and phenyl 2,3-anhydro-4,6- O -benzylidene-3-deoxy-3-nitro-β- d -allopyranoside, to give 2-substituted aldos-3-ulose derivatives. In the latter case, the subsequent β-elimination of the aglyconic phenyl group always occurred to afford the corresponding glycal. Reaction mechanisms thereof are also discussed.
摘要分别用甲基和苯基2,3-脱水-4,6-O-亚苄基-3-脱氧-3-硝基-β-d-吡喃吡喃糖苷处理了几个亲核试剂,得到了2-取代的aldos-3-ulose衍生物。在后一种情况下,总是发生随后的无糖基苯基的β-消除,以提供相应的糖基。还讨论了其反应机理。
