Generating alkyl radicals from the sulfonyl radicals remains challenging in synthetic chemistry. Here, we report an efficient photocatalyzed strategy using alkyl sodium sulfinates as both sulfonylating and alkylating reagents by controlling the reaction temperature. This methodology provides a versatile protocol for synthesizing diastereoselective sulfonylated cyclopropanes and poly-substituted styrene
从磺酰基自由基生成烷基自由基在合成化学中仍然具有挑战性。在这里,我们报告了一种通过控制反应温度,使用烷基亚磺酸钠作为磺酰化和烷基化试剂的有效光催化策略。该方法为合成非对映选择性磺酰化环丙烷和多取代苯乙烯衍生物提供了通用方案。该方法已通过多种环丙烯和烷基亚磺酸盐成功得到验证,展示了其广泛的底物范围、高非对映和E / Z选择性,并产生良好至优异的收率。
