  描述：

  1'-benzyl-5'-methoxy-1',3'-dihydrospiro-[cyclopropane-1,3'-indol]-2'-one 在 氨 、 sodium 、 magnesium iodide 作用下， 以 四氢呋喃 为溶剂， 反应 60.22h， 生成 horsfiline

  摘要：

  We report a short synthetic route to (+/-)-horsfiline that provides the racemate in five steps from commercially available, substituted isatin in 41% overall yield. Efficient entry into the spiro[oxindole-pyrrolidine] ring system is possible through the application of the cyclopropane opening/ring expansion chemistry we have described with MgI2 as a bifunctional catalyst.

• Domino Corey–Chaykovsky Reaction for One-Pot Access to Spirocyclopropyl Oxindoles
  作者：Saumen Hajra、Sayan Roy、SK Abu Saleh

  DOI：10.1021/acs.orglett.8b01840

  日期：2018.8.3

  The development of the sequential Corey–Chaykovsky reactions of isatins, spiroepoxy-, or spiroaziridine oxindoles with sulfur ylide has led to the discovery of a unique reaction mode that allows easy and direct one-pot access to a range of spirocyclopropyl oxindoles.

  靛红，螺环氧基或螺氮丙啶与吲哚硫醇的连续Corey-Chaykovsky反应的发展导致发现了一种独特的反应模式，该模式可以轻松，直接地一锅接触一系列螺环丙基羟吲哚。
• A Rapid Three-Component MgI₂-Mediated Synthesis of 3,3-Pyrollidinyl Spirooxindoles
  作者：Victoria Helan、Allie Mills、David Drewry、Daniel Grant

  DOI：10.1021/jo101077g

  日期：2010.10.1

  The rapid synthesis of 3,3-pyrrolidinyl-spirooxindole cores from readily available cyclopropyl spirooxindoles and commercially available aldehydes, amines, and sulfonamides is reported. This general procedure utilizes microwave heating to access a biologically privileged scaffold in an efficient route amenable to library population.
