A new copper-catalyzed oxysulfenylation reaction of enolates with sodium sulfinates has been disclosed. A series of sulfenylated heterocycles including four- and seven-membered cyclic ether were obtained in mild to good yields. This reaction is proposed to go through a radical process, and the sulfur radical (RS•) may be a reactive species.
已经公开了一种新的铜催化的烯醇盐与亚磺酸钠的氧磺酰化反应。以中等至良好的产率获得了一系列包括四元和七元环醚的亚磺酰基化杂环。建议该反应经过自由基过程,硫自由基(RS •)可能是反应性物质。
