• Tributyl(3,3,3-trifluoro-1-propynyl)stannane as an efficient reagent for the preparation of various trifluoromethylated heterocyclic compounds

  日期：2004.10

  1,3-dipolar cycloaddition of the stannane with diazomethane, phenylazide, and acetonitrile oxide smoothly proceeded to give the corresponding (tributylstannyl)trifluoromethyl-pyrazole, -triazole, and -isoxazole in good yields, respectively. These heterocyclic compounds are proved to be useful building blocks for the regioselective introduction of a functional group such as an aryl group or iodine.

  一步合成2-丁基-3,3,3-三氟丙烯很容易合成三丁基（3,3,3-三氟-1-丙炔基）锡烷。锡烷与重氮甲烷，苯叠氮化物和乙腈氧化物的1,3-偶极环加成反应顺利进行，分别以良好的产率得到相应的（三丁基锡烷基）三氟甲基-吡唑，-三唑和-异恶唑。这些杂环化合物被证明是用于区域选择性引入官能团例如芳基或碘的有用的结构单元。
