A Cu-catalyzed multicomponent cascade reaction of DABCO·(SO₂)₂ (DABSO), alcohol, and aryl diazonium tetrafluoroborate was developed which afforded sulfonic esters in moderate to good chemical yields. In this reaction, the SO₂ surrogate DABSO was used for the first time in the synthesis of sulfonic aliphatic esters. This multicomponent reaction was carried out under mild conditions and tolerated a wide range of substrates, which provides a new and efficient strategy for the synthesis of sulfonic esters.

铜催化的DABCO·（SO ₂）₂，醇和芳基重氮鎓的多组分反应合成磺酸酯

开发了铜催化的DABCO·（SO ₂）₂（DABSO），醇和四氟硼酸芳基重氮鎓的多级联反应，能够以中等至良好的化学收率提供磺酸酯。在该反应中，SO ₂替代DABSO首次用于磺酸脂族酯的合成。这种多组分反应是在温和的条件下进行的，可耐受多种底物，这为合成磺酸酯提供了新的有效策略。
