• Mechanistic Insight into the Formal [1,3]-Migration in the Thermal Claisen Rearrangement
  作者：Shili Hou、Xinyao Li、Jiaxi Xu

  DOI：10.1021/jo302210t

  日期：2012.12.7

  computational studies reveal that the concerted C[1,3]-sigmatropic shift suffered from a higher energetic barrier to allow the rearrangement to proceed under the conditions used. However, a tandem O[1,3]-sigmatropic shift with a configuration inversion of the oxygen atom and [3,3]-sigmatropic shift (the Claisen rearrangement) is the most likely pathway for the formal [1,3] rearrangement. Furthermore, the rearrangement

  借助B3LYP函数的密度泛函理论（DFT）计算，对烯丙基芳基醚的热形式[1,3]-σ位移进行了深入的实验研究。先前已经提出了三种机制的可能性，分别称为自由基，离子和协同机制，以解释热[1,3]重排过程。但是，交叉和自由基捕获实验表明重排是分子内过程。计算研究表明，协调的C [1,3]-σ位移受较高的能垒的影响，可以在所使用的条件下进行重排。但是，串联的O [1,3]-σ位移与氧原子和[3，3]-正移（Claisen重排）是形式上[1,3]重排的最可能途径。此外，使用设计的光学活性基板和O [1,3]-σ位移示例进行的重排实验验证了新的级联重排。此外，计算和实验研究表明，水分子有助于异构化过程中的质子移动。组合方法为Claisen重排中的热形式[1,3]迁移机理以及新颖的O [1,3]-σ位移提供了新的见解。计算和实验研究表明，水分子有助于异构化过程中的质子移动。组合方法为Claisen重排中的热形式[1

  Cool and compatible: Aryl mesylates and tosylates underwent palladium‐catalyzed cyanation under mild, aqueous conditions at 65–80 °C (see scheme). In many cases, water could be used as the reaction medium without a cosolvent, and a variety of substituents R, such as keto, aldehyde, ester, free amine, and nitrile groups, remained intact during the transformation.

  作者：Christopher J. Dinsmore、C.Blair Zartman

  日期：1999.5

  protecting group for a phenol is conveniently unmasked under the conditions of the SNAr reaction with an activated aryl halide, producing diarylether products directly. The method is advantageous when the preparation of a phenol substrate requires O-protection, since the selection of the robust methanesulfonate as a latent phenol obviates a deprotection step prior to the SNAr reaction.
