  • Enantioselective Organocatalytic Iodination-Initiated Wagner–Meerwein Rearrangement
    作者:Fedor Romanov-Michailidis、Laure Guénée、Alexandre Alexakis
    DOI:10.1021/ol402981z
    日期:2013.11.15
    The present manuscript describes a high-yielding enantioselective semipinacol transposition, initiated by an electrophilic iodination event. The title transformation makes use of the anionic phase-transfer catalysis (PTC) paradigm for chirality induction. Thus, when combined appropriately, the insoluble cationic iodinating reagent S9 and the lipophilic phosphoric acid L9 act as an efficient source
    本手稿描述了由亲电子碘化事件引发的高产量对映选择性半松果醇酯转座。标题转换利用阴离子相转移催化(PTC)范式进行手性诱导。因此,当适当组合时,不溶性阳离子碘化试剂S 9和亲脂性磷酸L 9可以作为有效的手性碘源,将应变的烯丙醇A x转化为β-碘螺酮B x进行半频哪醇转化。产量高,非对映和对映体诱导水平高。β-碘螺环酮产品可以立体定向衍生而没有立体侵蚀,从而导致直接从半松果醇重排中无法获得的产品。
  • Enantioselective Halocyclization Using Reagents Tailored for Chiral Anion Phase-Transfer Catalysis
    作者:Yi-Ming Wang、Jeffrey Wu、Christina Hoong、Vivek Rauniyar、F. Dean Toste
    DOI:10.1021/ja305795x
    日期:2012.8.8
    A chiral anion phase-transfer system for enantioselective halogenation is described. Highly insoluble, ionic reagents were developed as electrophilic bromine and iodine sources, and application of this system to o-anilidostyrenes afforded halogenated 4H-3,1-benzoxazines with excellent yield and enantioselectivity.
  • Enantioselective Halogenative Semi-Pinacol Rearrangement: Extension of Substrate Scope and Mechanistic Investigations
    作者:Fedor Romanov-Michailidis、Maria Romanova-Michaelides、Marion Pupier、Alexandre Alexakis

    the heavier halogens (bromine and iodine) second, the scope and limitations of the halogenative phase‐transfer methodology will be discussed and compared. An extension of the fluorination/semi‐pinacol reaction to the ring‐expansion of five‐membered allylic cyclopentanols will be also described, as well as some preliminary results on substrates prone to desymmetrization will be given. Finally, the present
    本文全文对我们在对映选择性卤化引发的半频哪醇重排中获得的最新结果进行了调查。首先从氟化/半频哪醇反应开始,然后转向较重的卤素(溴和碘),将讨论和比较卤化相转移方法的范围和局限性。还将描述氟化/半频哪醇反应对五元烯丙基环戊醇扩环的扩展作用,并给出了易于脱对称的底物的一些初步结果。最后,本手稿将以规范的氟化/半频哪醇反应的详细机理研究为结尾。我们的机理讨论将基于原位反应进度监控,
