Copper-catalyzed, one-pot, three-component coupling reactions using thiols, alcohols, and oxygen to form a variety of esters in good yields were studied. In the presence of easily oxidized benzylic and allylic alcohols, thiols were selectively oxidized to form thionoesters, which underwent facile S/O exchange to afford esters. Thiols may be used as an alternative benzoyl source under mild aerobic conditions
研究了使用硫醇、醇和氧以良好产率形成各种酯的铜催化、一锅、三组分偶联反应。在易氧化的苄醇和烯丙醇存在下,硫醇被选择性氧化形成硫酮酯,硫醇酯经过简单的 S/O 交换得到酯。在温和的有氧条件下,硫醇可用作替代苯甲酰来源。
