for the preparation of 3-substituted isocoumarins via palladium-catalyzed nucleophilic addition/oxidative annulation of bromoalkynes with benzoic acids has been developed. Remarkably, preliminary mechanistic studies indicated that the transformation might proceed via a stereo- and regioselective nucleophilic addition and C–H functionalization procedure.
已经开发了通过钯催化的溴炔烃与苯甲酸的亲核加成/氧化环化反应制备3-取代的香豆素的有效而有效的方案。值得注意的是,初步的机理研究表明,转化可能通过立体和区域选择性亲核加成和CH功能化程序进行。
