A first example of simple and efficient hydrophilic Pd-phosphine complexes catalyzed one-pot three-component reaction of ortho-bromo aldehydes, terminal alkynes and ammonium acetate proceeds through the tandem coupling-imination-annulation path for the synthesis of substituted isoquinolines, furopyridines and thienopyridines in good to excellent yields in green aqueous medium at mild temperature was
简单有效的亲水性Pd-膦配合物催化邻溴代乙醛,末端炔烃和乙酸铵的单锅三组分反应的第一个例子是通过串联偶联-胺化-环化路径进行的,用于合成取代的异喹啉,呋喃吡啶和描述了噻吩并吡啶在温和的温度下在绿色水性介质中具有良好至极好的收率。
