A sequential one‐pot two‐step reaction for efficient synthesis of pyrrolo[2,1‐a]isoquinoline and pyrrolo[1,2‐a]quinoline derivatives in good yields has been successfully developed. The reaction included firstly Cu‐catalyzed three‐component reaction of isoquinoline (quinoline), acetylenedicarboxylate and alkynylbenzene and then Pd‐catalyzed intramolecular C(sp)‐C(sp2) coupling reaction of initially
已经成功开发了以高收率高效合成吡咯并[2,1- a ]异喹啉和吡咯并[1,2- a ]喹啉衍生物的顺序一锅两步反应。该反应首先包括铜催化的异喹啉(喹啉),乙炔基羧酸盐和炔基苯的三组分反应,然后钯催化的最初形成的1-烯基-2-炔基-1的分子内C(sp)-C(sp 2)偶联反应。 ,2-二氢异喹啉(1,2-二氢喹啉)。
