novel, efficient, and facile vicinal sulfonamination of alkynes by the reaction of accessible 2-alkynyl arylazides with sulfinic acids in the presence of tert-butyl hydroperoxide (TBHP) has been developed. This protocol utilizes sulfinic acids as the sulfonating reagent, azidos as the aminating reagent, and TBHP as the sulfonyl radical initiator. By using this protocol, a variety of potentially bioactive
通过在叔丁基氢过氧化物(TBHP)存在下,可及的2-炔基芳基叠氮化物与亚磺酸的反应,开发了一种新颖,有效且简便的炔烃磺酰胺化方法。该协议使用亚磺酸作为磺化试剂,叠氮基作为胺化试剂,TBHP作为磺酰基自由基引发剂。通过使用此协议,可以通过直接环切轻松地合成各种潜在的具有生物活性的3-磺酰吲哚。
