A simple and selective synthetic method of quinolines and indoles by the reaction of β-(2-nitrophenyl)-α,β-unsaturated ketones with carbon monoxide was developed. When β-(2-nitrophenyl)-α,β-unsaturated ketones were allowed to react with carbon monoxide and water in the presence of a stoichiometric amount of sulfur or a catalytic amount of selenium, the corresponding quinolines were produced in moderate-to-good
开发了一种通过β-(2-硝基苯基)-α,β-不饱和酮与一氧化碳反应合成喹啉和吲哚的简单且选择性的方法。当 β-(2-硝基苯基)-α,β-不饱和酮在化学计量量的硫或催化量的硒存在下与一氧化碳和水反应时,相应的喹啉以中等至-良好的收益。另一方面,在没有水的情况下,吲哚是通过 β-(2-硝基苯基)-α,β-不饱和酮与一氧化碳的硒催化反应产生的。
