  • Stereocontrolled synthesis of C10-C22 fragment of the immunosuppressant FK 506. An occurrence of complementary stereoselectivity in the C15 ketone reduction
    作者:Yoshiki Morimoto、Atsushi Mikami、Shin-itsu Kuwabe、Haruhisa Shirahama
    DOI:10.1016/s0957-4166(96)00445-4
    日期:1996.12
    stereocontrolled ester-enolate Claisen rearrangement of ene-ester 5, and the aldehyde 4 which was prepared from D-mannitol via anti selective methallylsilane addition to aldehyde 6 followed by modest stereoselective hydroboration based on 1,3-asymmetric induction. In the course of this reaction sequence a complementary stereoselection dependent on the used hydride reagents has occurred in reduction of the coupling
    免疫抑制剂FK 506 1的C10-C22片段2a及其C15-受体2b的立体选择性合成是通过砜3的会聚偶联完成的,该偶联可通过高度立体控制的烯酸酯的酯-烯酸酯克莱森重排来构建5和由D-甘露糖醇经反选择性甲基烯丙基硅烷加成醛6制备的醛4然后进行基于1,3-不对称诱导的适度立体选择性硼氢化反应。在该反应过程中,依赖于所用氢化物试剂的互补的立体选择发生在偶联产物26的还原中。
  • Unprecedented stability of δ-lactones with axial substituents rather than equatorial ones; comparison with the Prelog–Djerassi lactone derivative
    作者:Yoshiki Morimoto、Atsushi Mikami、Haruhisa Shirahama
    DOI:10.1039/c39910001376
    日期:——
    A 1 : 1 mixture of the trisubstituted δ-lactones 11a and 11b was subjected to thermodynamically equilibrated conditions to give predominantly 11b with axial substituents rather than 11a with all equatorial ones, in contrast to the Prelog–Djerassi lactone derivatives 3a and 3b, and, further surprisingly, it has been found that the disubstituted lactone 10 also adopts a chair conformation with axial substituents.
    在热力学平衡条件下,三取代δ-内酯 11a 和 11b 的 1 : 1 混合物主要产生具有轴向取代基的 11b,而不是全部具有赤道取代基的 11a,这与 PrelogâDjerassi 内酯衍生物 3a 和 3b 形成鲜明对比。
  • Unexpected stability of δ-lactones with axial substituents rather than equatorial ones. Conformational evaluation by molecular mechanics and molecular orbital calculations
    作者:Yoshiki Morimoto、Haruhisa Shirahama
    DOI:10.1016/s0040-4020(96)01138-6
    日期:1997.2
    trisubstituted δ-lactones 5a and 5b was subjected to thermodynamically equilibrated conditions to give predominantly 5b with axial substituents rather than 5a with all equatorial ones, in contrast to the Prelog-Djerassi lactone derivatives 3a and 3b. Further surprisingly, it has been found that the disubstituted lactone 15 also adopts a half-chair conformation with axial substituents. The conformational analyses
    与Prelog-Djerassi内酯衍生物3a和3b相反,将三取代的δ-内酯5a和5b的1:1混合物置于热力学平衡的条件下,主要得到具有轴向取代基的5b而不是所有赤道取代基5a。进一步令人惊奇地发现,二取代的内酯15也采用带有轴向取代基的半椅构型。通过分子力学和分子轨道计算对这些化合物进行的构象分析强调了网状效应和静电相互作用,这是偏向于轴向构象异构体的原因。
