A new Prins cyclization process that builds up one carbon−carbon bond, one heteroatom-carbon bond, and one halogen-carbon bond, (in an oxa- and azacycle) relies on an iron catalyst system formed from Fe(acac)3 and trimethylsilyl halide. The method displays a broad substrate scope and is economical, environmentally friendly, and experimentally simple. This catalytic method permits the construction of
新的Prins环化过程建立一个碳-碳键,一个杂原子-碳键和一个卤素-碳键(在氧杂和氮杂环中)依赖于由Fe(acac)3和三甲基甲硅烷基形成的铁催化剂体系卤化物。该方法显示出广泛的底物范围,并且经济,环境友好并且实验简单。该催化方法允许通过铁(III)源,相应的三甲基甲硅烷基卤化物和溶剂的适当组合以高收率构造氯,溴和碘杂环。
