Reduction of 2-(2-nitrophenyl)-2-cyclohexene-1-ones using palladium on carbon under 1 atm of hydrogen gas at ambient temperature affords 1,2,3,4-tetrahydrocarbazoles in excellent isolated yields. The starting materials were prepared by intermolecular Stille coupling of 2-iodo-2-cyclohexen-1-ones with 2-(tributylstannyl)-1-nitrobenzenes.
在室温下在氢气中,在1个大气压下,使用钯碳还原2-(2-硝基苯基)-2-环己烯-1-酮,可得到1,2,3,4-四氢咔唑,分离产率极佳。通过2-碘-2-环己烯-1-酮与2-(三丁基锡烷基)-1-硝基苯的分子间Stille偶联制备起始原料。
