protocol was developed for the preparation of allylic sulfones through direct condensation of sodium arylsulfinates and β,β-disubstituted nitroalkenes. The key step of this process was the Lewis base-promoted equilibrium between nitroalkenes and allylic nitro compounds. Through this process, the readily available conjugated nitroalkenes can be easily converted into allylic nitro compounds, which contain
开发了一种无金属的开放烧瓶规程,用于通过芳基亚磺酸钠和β,β-二取代的硝基烯烃的直接缩合制备烯丙基砜。该过程的关键步骤是硝基烯烃与烯丙基硝基化合物之间的路易斯碱促进的平衡。通过该方法,容易获得的共轭硝基烯烃可以容易地转化为烯丙基硝基化合物,其对磺酰基自由基加成包含更多的反应性C═C键。结果,在温和条件下以优异的产率制备了烯丙基砜,具有广泛的底物范围。
