A visible-light-induced, Eosin Y catalyzed three-component synthesis of 3-arylsulfonylquinoline derivatives through N-propargyl aromatic amines, diaryliodonium salts and sulfur dioxide has been discovered. This transformation represents an efficient and attractive method for the straightforward synthesis of 3-arylsulfonylquinoline derivatives via the formation of C–S bonds and quinolines in one step. In addition, it exhibits good substrate scope and functional group tolerance. The use of easy-to-handle diaryliodonium salts, sulfur dioxide sources and the cheap photocatalyst Eosin Y together with facile operation at room temperature makes this protocol very practical.

可见光诱导的多组分级联环加成反应，涉及N-炔丙基芳族胺，二芳基碘鎓盐和二氧化硫：快速获得3-芳基磺酰基喹啉

已经发现了可见光诱导的曙红Y通过N-炔丙基芳族胺，二芳基碘鎓盐和二氧化硫催化的3-芳基磺酰基喹啉衍生物的三组分合成。这种转变代表了通过一步形成C–S键和喹啉直接合成3-芳基磺酰基喹啉衍生物的一种有效且有吸引力的方法。另外，它表现出良好的底物范围和官能团耐受性。易处理的二芳基碘鎓盐，二氧化硫源和廉价的光催化剂曙红Y的使用以及在室温下的简便操作，使该方案非常实用。
