  • Probing the Mechanism of Allylic Substitution of Morita–Baylis–Hillman Acetates (MBHAs) by using the Silyl Phosphonite Paradigm: Scope and Applications of a Versatile Transformation
    作者:Maria Kalyva、Alexandros L. Zografos、Era Kapourani、Evaggelos Giambazolias、Laurent Devel、Athanasios Papakyriakou、Vincent Dive、Yannis G. Lazarou、Dimitris Georgiadis

    日期:2015.2.16
    using 31P NMR spectroscopy revealed unexpected reactivity differences between ester and nitrile derivatives. These kinetic profiles and DFT calculations support a mechanistic scenario in which observed differences can be explained from the “lateness” of transition states. In addition, we provide experimental evidence suggesting that enolates due to initial P‐Michael addition are not formed. Based on
    AP 甲硅烷基膦酸酯和森田-的Baylis-希尔曼乙酸盐(MBHAs)之间C键形成反应探索作为向医药相关β-carboxyphosphinic结构基序的通用的替代方案。使用31记录的不同取代的MBHA转化为次膦酸9或14的转化率P NMR光谱显示酯和腈衍生物之间的反应性差异出乎意料。这些动力学曲线和DFT计算支持了一种机械方案,其中可以从过渡态的“迟缓”解释观察到的差异。此外,我们提供的实验证据表明,由于最初的P-Michael加成而形成的烯醇不形成。基于拟议的机械情景结合DFT计算,对E / Z的解释提出了酯和腈之间的立体选择性差异。提出了由这种转变产生的合成机会,该机会涉及几种合成的反复变化的膦基结构单元的制备,而这些结构单元通过经典的P-Michael合成路线的访问并不简单。
  • The Enantioselective Synthesis of Chiral Carbocyclic Nucleosides via Palladium‐Catalyzed Asymmetric Allylic Amination of Alicyclic MBH Adducts with Purines
    作者:Bo Kang、Qi‐Ying Zhang、Gui‐Rong Qu、Hai‐Ming Guo
    DOI:10.1002/adsc.202000088
    日期:2020.5.12
    The enantioselective synthesis of carbocyclic nucleosides through the palladium‐catalyzed asymmetric allylic amination of alicyclic Morita‐Baylis‐Hillman (MBH) adducts with purines was successfully developed. With a combination of Pd2(dba)3/L7 as catalyst, various optically active carbocyclic nucleosides featuring a C=C double bond in the carbocycle moiety were obtained in high yields (up to 97%) with
    通过钯催化的嘌呤与脂环式森田-贝利斯-希尔曼(MBH)加合物的钯催化不对称烯丙基胺化,成功开发了碳环核苷的对映选择性合成。结合使用Pd 2(dba)3 / L7作为催化剂,可以以高收率(高达97%)和优异的N 9 / N 7-获得各种在碳环部分具有C = C双键的旋光碳环核苷。选择性(> 95/5)和对映选择性(> 99.6%)。另外,这些核苷类似物允许快速转化为多种其他有趣的结构上不同的手性碳环核苷。
  • Concise formal synthesis of (−)-7-deoxyloganin via N-heterocyclic carbene catalysed rearrangement of α,β-unsaturated enol esters

    NHC catalysed rearrangement of α,β-unsaturated enol esters derived from formyl acetates and cyclopentyl annulated α,β-unsaturated acids provides the cyclopentapyranone core of (−)-7-deoxyloganin (1) with diastereo- and chemoselectivity in 6 steps starting from (−)-citronellal. The elaboration to the natural product has been investigated using two new approaches. The most successful intercepts our previous
    NHC催化从乙酸甲酰酯和环戊基环化的α,β-不饱和酸衍生的α,β-不饱和烯醇酯的重排为(-)-7-脱氧丹宁(1)的环戊吡喃酮核心提供了从6开始的非对映异构和化学选择性(-)-香茅醛。已使用两种新方法研究了对天然产物的精加工。最成功的方法是拦截我们先前在(-)-7-deoxyloganin(1)上的工作,从而允许完成10个步骤的正式总合成。
  • Resolution and Utilization of Ethyl 5-Hydroxycyclopent-1-enecarboxylate: Enantioselective Synthesis of (+)-Mitsugashiwalactone and (-)-Dolichodial
    作者:Takahiro Yamane、Michiyasu Takahashi、Kunio Ogasawara
    DOI:10.1055/s-1995-3930
    日期:1995.4
    Optically pure ethyl 5-hydroxycyclopent-1-enecarboxylate has been obtained with its acetate in both enantiomeric forms in excellent optical yields from racemic ethyl 5-hydroxycyclopent-1-enecarboxylate by lipase-mediated kinetic resolution. The optically pure (R)-enantiomer thus obtained has been transformed into two naturally occurring iridoid monoterpenes, (+)-mitsugashiwalactone and (-)-dolichodial.

  • Intramolecular Baylis−Hillman and Morita Reactions Using Unsaturated Thiol Ester Substrates Containing Enolizable Aldehydes
    作者:Gary E. Keck、Dennie S. Welch
    DOI:10.1021/ol026638s
    日期:2002.10.1
    [reaction: see text] Previously unknown intramolecular Baylis-Hillman and Morita reactions involving cyclization of an unsaturated thiol ester onto a pendant aldehyde function are reported. These can be used successfully for the preparation of both cyclopentenols and cyclohexenols, but the results are very sensitive to substrate and precise reaction conditions.
