A novel and efficient synthesis of pyrrolo[3,2,1-kl]phenothiazines has been developed through a Cu(I)-catalyzed tandem C–S coupling/double cyclization process. Using 2-alkynyl-6-iodoanilines and o-bromobenzenethiols as the starting materials, a wide range of pyrrolo[3,2,1-kl]phenothiazine derivatives were facilely and efficiently generated in one pot under Cu(I) catalysis.
通过Cu(I)催化的串联C–S偶联/双环化过程,开发了一种新型且高效的吡咯并[3,2,1- kl ]吩噻嗪合成方法。以2-炔基-6-碘苯胺和邻溴代苯硫酚为原料,在Cu(I)催化下,在一个锅中轻松高效地生成了多种吡咯并[3,2,1- kl ]吩噻嗪衍生物。
