• Design and Synthesis of Novel Chiral Dirhodium(II) Carboxylate Complexes for Asymmetric Cyclopropanation Reactions

  日期：2016.3.1

  the design of dirhodium(II) tetracarboxylates derived from (S)‐amino acid ligands is reported. The approach is founded on tailoring the steric influences of the overall catalyst structure by reducing the local symmetry of the ligand's N‐heterocyclic tether. The application of the new approach has led to the uncovering of [Rh2(S‐tertPTTL)4] as a new member of the dirhodium(II) family with extraordinary

  报道了一种新颖的设计从（S）-氨基酸配体衍生的四羧酸二（二）铑（II）的方法。该方法的基础是通过减少配体的N杂环系链的局部对称性来调整整个催化剂结构的空间影响。新方法的应用已导致的揭露的[Rh 2（小号-叔PTTL）4 ]作为二铑（II）家族在环丙烷化反应非凡选择性的新成员。发现[Rh 2（S - tert PTTL）4 ]的立体选择性与[Rh 2（S‐PTAD）4 ]（ee高达99％以上），其附加优点是可以通过综合方式访问。还讨论了基于X射线结构的相关性以证明观察到的对映体诱导是正当的。

  Vinyl sulphones (1) were subjected to nucleophilic addition by α-lithionitriles (2) and gave cyclized products, 3-oxothian 1,1-dioxides (3) or cyclopropane derivatives (4), in satisfactory yields according to the substituents on the reagents. The cyclopropanation reactions could be extended to the formation of cyclopropyl sulphides (12)–(16) in good yields.

  根据试剂上的取代基，以令人满意的收率，将乙烯基砜（1）通过α-锂离子（2）进行亲核加成，得到环化产物3-氧杂环丁烷1,1-二氧化物（3）或环丙烷衍生物（4）。 。环丙烷化反应可以以高收率扩展到环丙基硫化物（12）-（16）的形成。
• Reactions of Hypervalent Iodonium Alkynyl Triflates with Azides: Generation of Cyanocarbenes
  作者：I. F. Dempsey Hyatt、Mitchell P. Croatt

  DOI：10.1002/anie.201203062

  日期：2012.7.23

  time: Cyanocarbenes have been formed by the reaction of azides with hypervalent iodonium alkynyl triflates (HIATs). Experimental evidence supports the potential intermediacy of an azide‐substituted vinylidene or alkynyl azide, both of which could form a cyanocarbene. Trapping of the vinylidene and cyanocarbene includes OH insertion, dimethyl sulfoxide coordination, and cyclopropanation reactions.

  organocatalytic method for the stereoselective synthesis of highly substituted cyclopropanes is reported. The Michael adducts, generated through the addition of α-substituted cyanoacetates to easily accessible vinyl selenones catalyzed by a bifunctional ureidic catalyst, smoothly cyclize by intramolecular alkylation induced by a de-ethoxycarbonylation process. The one-pot sequence generates cyclopropanes

  Efficient cyclopropanation reactions of aryl or styrylacetonitriles with vinyl selenones under mild conditions were described. By this approach, synthetically challenging 1‐vinylcyclopropane‐1‐carbonitriles were accessible in good yields. This methodology features the advantage of operational simplicity, broad substrate scope, good functional group tolerance, transition‐metal‐free conditions, mild temperature, and a high level of regio‐ and diastereo‐control.
