  • Rational Design of Aldol Reactions That Proceed via Kinetic Resolution with Switchable Enantioselectivity
    作者:Dale E. Ward、Fabiola Becerril-Jimenez、M. Mehdi Zahedi
    DOI:10.1021/jo900716a
    日期:2009.6.19
    hydroxy-protected derivatives of ketone 1 (R = MOM, Et3Si, or Ac) undergo aldol reactions with high diastereoface selectivity to give 3,5-trans adducts. High levels of anti and syn relative topicity were obtained with dicyclohexylboron enolates and Ti(OiPr)4Li “ate” enolates, respectively. Using these enolates, aldol reactions of (±)-2 with (±)-1 gave two of the eight possible diastereomeric adducts (3 from
    手性反应物的醛醇缩合反应的立体选择性可以分解为三个立体控制元素:酮烯醇和醛的非对映体选择性以及偶联的相对局部性。将乘法规则应用于这些元素会导致以下预测:如果所有三个立体声控制元素都受到强烈偏置,则动力学分辨率(KR)应该是可能的。因此,动力学分辨率的对映选择性应可通过改变任何立体控制元件的选择性来切换。使用具有高非对映选择性的醛和酮反应物并开发了强烈支持顺式或反式相对位置性的反应条件,对这一假设进行了测试。醛2进行具有几乎排他的Felkin非对映体选择性的醛醇缩合反应,酮1的羟基保护衍生物(R = MOM,Et 3 Si或Ac)进行非对映体选择性高的醛醇缩合反应,得到3,5-反式加合物。的高水平的抗和顺式与钛(O dicyclohexylboron烯醇化物并得到相对topicity我PR)4分别李“吃”烯醇化物。使用这些烯醇化物,(±)-2与(±)-1的醛醇缩合反应可得到八种可能的非对映异
  • Enantioselective Direct Intermolecular Aldol Reactions with Enantiotopic Group Selectivity and Dynamic Kinetic Resolution
    作者:Dale E. Ward、Vishal Jheengut、Olukayode T. Akinnusi

    日期:2005.3.1
    4-dioxa-8-thiaspiro[4.5]decane-6,10-dicarboxaldehyde proceed with dynamic kinetic resolution and give single adducts in good yields with excellent ee's. The high enantiotopic group selectivity results from the high intrinsic diastereoface selectivity of the aldehydes. These reactions significantly extend the scope of the enantioselective direct aldol reaction and constitute simple and efficient syntheses of
    [反应:见正文]四氢-4H-吡喃酮与外消旋1,4-二氧杂-8-硫杂螺[4.5]癸烷-6-甲醛和内消旋/ dl 1,4-二氧杂-8的脯氨酸催化的羟醛反应-thiaspiro [4.5] decane-6,10-dibarboxaldehyde可进行动态动力学拆分,并以良好的ee收率获得高收率的单加合物。高对映体基团选择性是由于醛的高固有非对映异构体选择性所致。这些反应显着扩展了对映选择性直接醛醇缩合反应的范围,并且构成有用的四丙酸酯合成子的简单而有效的合成。
  • Total Synthesis of Muamvatin

    日期:2012.12.21
    tautomerization of an acyclic derivative assembled by sequential substrate-controlled stereoselective aldol reactions of a chiral ketone with two achiral aldehydes. Although the trioxaadamantane tautomer was shown to be thermodynamically more stable than alternative forms, the kinetic barrier to cyclization was significant. This observation raises doubts about the proposed formation of muamvatin as an
    muamvatin的对映选择性全合成是通过无环衍生物的环链互变异构而实现的,该无环衍生物是由手性酮与两个非手性醛的连续底物控制的立体选择性醛醇缩合反应组装而成的。尽管显示三恶金刚烷互变异构体在热力学上比替代形式更稳定,但是环化的动力学障碍是显着的。这一观察结果使人们怀疑拟定形成的muamvatin是一种分离产物。
  • Synthetic Studies on Siphonariid Polypropionates: Synthesis and Isomerization of the Caloundrin B Trioxaadamantane Ring System
    作者:Garrison E. Beye、Jonathan M. Goodman、Dale E. Ward

    日期:2009.3.19
    (1R,3R,5R,7R,8S,9R,10S)-3,5-Diethyl-8,9,10-trimethyl-2,4,6-trioxatricyclo[3.3.1.1(3,7)]decan-1-ol (II), a model of the trioxaadamantane ring system embedded in caloundrin B, was prepared by isomerization of the thermodynamically unstable (9S)-diastereomer (1) in the presence of imidazole. Alternatively, isomerization of I with HF.py or DBU gave the hemiacetal III or its retro-Claisen ester IV, respectively, which represent structural motifs present in the closely related siphonariid polypropionates siphonarin B and baconipyrone C.

  • On the Origin of Siphonariid Polypropionates: Total Synthesis of Baconipyrone A, Baconipyrone C, and Siphonarin B via their Putative Common Precursor
    作者:Garrison E. Beye、Dale E. Ward

    日期:2010.5.26
    rearrangement was directly engaged in aldol cyclization while baconipyrone C resulted from simple ketonization of the enol(ate). These experiments provide the first unambiguous demonstration that the baconipyrones are plausible isolation artifacts and suggest they are most likely derived from siphonarins rather than an "acyclic" precursor. Caloundrin B was not detected among the products from any of the isomerization
    通过检查 S. zelandica 十丙酸酯 siphonarin B、caloundrin B、baconipyrone A 和 baconipyrone C 的假定共同前体的特性,测试了 siphonariid polypropionates 源自对无环生物合成前体的非酶促过程的假设,即(4S,5S, 6S,8RS,10S,11S,12R,14R)-14-(6-ethyl-3,5-dimethyl-4-oxo-4H-pyran-2-yl)-5,11-dihydroxy-4,6,8 ,10,12-pentamethylpentadecane-3,7,9,13-tetraone。使用基于噻喃的聚丙酸酯合成策略,以有效且完全对映选择性的方式实现了此类前体的首次合成。这种推定的前体是环链互变异构体和酮-烯醇互变异构体的复杂混合物,在动力学上是稳定的,并且异构化为热力学更稳定的虹吸素 B。在咪唑
