An efficient synthetic route towards the synthesis of β-keto sulfones has been developed from secondary benzyl alcohols using N-bromosuccinimide (NBS). The present protocol utilizes NBS as oxidant as well as brominating agent, readily accessible benzyl alcohols and sodium arenesulfinates as the sulfonylating reagent under mild conditions. The control experiments revealed that the reaction proceeds
已经使用N-溴代琥珀酰亚胺(NBS)由仲苄醇开发了一种有效的合成β-酮砜的合成途径。本协议在温和的条件下利用NBS作为氧化剂和溴化剂,易于获得的苯甲醇和芳烃亚磺酸钠作为磺酰化试剂。对照实验表明,反应是通过醇氧化为酮,酮的α-溴化和芳烃亚磺酸钠的亲核取代反应进行的。此外,该方法的效率用克级反应进行了测试,并显示了合成效用。
