deoxygenation of sulfoxides based on a novel application of chlorosulfonium salts and demonstrate a new process using these species generated in situ from sulfoxides as the source of electrophilic chlorine. The use of highly nucleophilic 1,3,5‐trimethoxybenzene (TMB) as the reducing agent is described for the first time and applied in the deoxygenation of simple and functionalized sulfoxides. The method
本文中,我们基于氯ulf盐的新应用描述了亚砜的选择性后期脱氧,并展示了使用这些亚砜原位生成的物种作为亲电氯源的新工艺。首次描述了使用高度亲核的1,3,5-三甲氧基苯(TMB)作为还原剂,并将其用于简单和功能化亚砜的脱氧。该方法易于操作,经济,适用于克级操作,并且易于应用于多官能分子,如超过45个实例(包括商业药物和类似物)所示。我们还报告了定义更具反应性的亚砜的竞争实验的结果,并且我们根据底物和产品的观察结果提出了一种机械的方案。
