The sulfur-mediated difunctionalization of alkynes is reported to give α-acetoxy ketones in a one-pot operation under mild conditions with 19-92% yield. By using wet potassium acetate as both the aqueous base and nucleophilic reagent, both terminal alkynes and internal alkynes could be converted into the α-acetoxy ketone products.
据报道,炔烃的硫介导的双官能团化可以在温和的条件下,通过一锅操作以19-92%的收率得到α-乙酰氧基酮。通过使用湿乙酸钾作为碱水溶液和亲核试剂,末端炔烃和内部炔烃都可以转化为α-乙酰氧基酮产物。
