The first synthesis of methoxy-substituted exocyclic (E)- and (Z)-unsaturated methyl pyranosides is reported involving the syn elimination of a selenoxide derivative as a key step. The rearrangement of these exocyclic enol ethers in the presence of TIBAL and DIBAL-H is also described. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
据报道,甲氧基取代的环外 (E)-和 (Z)-不饱和甲基吡喃糖苷的首次合成涉及作为关键步骤的硒氧化物衍生物的顺式消除。还描述了在 TIBAL 和 DIBAL-H 存在下这些环外烯醇醚的重排。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
