摘要
具有三环[2.2.1.0^(2,6)]庚烷结构单元的天然产物表现出广泛的生物学活性,因此开发合成三环[2.2.1.0^(2,6)]庚烷衍生物的新方法具有重要意义。研究了铜催化的降冰片烯硫化反应,合成了系列苯硫基三环[2.2.1.0^(2,6)]庚烷衍生物。以降冰片烯和二硫醚为原料,碘化亚铜为催化剂,二甲基亚砜(DMSO)为溶剂,150℃空气氛围下反应4 h,最终以66%~96%的产率获得相应产物。其结构经^(1)H NMR,^(13)C NMR和HR-MS进行了确证,并确定了单晶分子结构。该反应具有原料简单易得,催化剂廉价和操作简单等优点。
Natural products with tricyclo[2.2.1.0^(2,6)]heptane structural units display a wide range of biological activities.Therefore,it is of great significance to develop new methods for the synthesis of tricyclo[2.2.1.0^(2,6)]heptane derivatives.Herein,copper-catalyzed sulfuration of norbornene was studied and synthesized a series of phenylthiotricyclo[2.2.1.0^(2,6)]heptane derivatives.The corresponding products were finally obtained in the yield of 66%~96%,using norbornene and disulfides as raw materials,CuI as catalyst,dimethyl sulfoxide(DMSO)as the solvent,reacted at 150℃for 4 hours under air.The structures were characterized by^(1)H NMR,^(13)C NMR and HR-MS,and were confirmed by single crystal structures.This reaction has the advantages of using readily available substrates,cheap catalyst and simple operation.
