neither an oxidant nor additional solvent. The developed protocol tolerates a wide range of functional groups including methyl, methoxy, fluoro, chloro, and in particular the formyl group. This new strategy is highly regioselective and provides aryl methyl sulfides from 2-phenyl pyridines in moderate to good yields.
描述了使用DMSO作为甲硫基来源和氨基酸配体的2-苯基吡啶的CHH甲硫基化的新方案。这个简单的步骤既不需要氧化剂也不需要额外的溶剂。所开发的方案可耐受各种官能团,包括甲基,甲氧基,氟,氯,尤其是甲酰基。这种新的策略具有很高的区域选择性,可以以中等到良好的产率从2-苯基吡啶提供芳基甲基硫化物。
