Palladium(0)-catalyzed Domino C-N Coupling/Hydroamination/C-H Arylation: Efficient Synthesis of Benzothieno[2′,3′:4,5]pyrrolo[1,2-f]phenanthridines was written by Salman, Ghazwan Ali;Pham, Ngo Nghia;Ngo, Thang Ngoc;Ehlers, Peter;Villinger, Alexander;Langer, Peter. And the article was included in Advanced Synthesis & Catalysis in 2017.Product Details of 6287-82-7 This article mentions the following:
Two new and efficient routes to benzothieno[2′,3′:4,5]pyrrolo[1,2-f]phenanthridines were developed. Alkynylated benzothiophenes reacted with various anilines to the target compounds in a domino reaction consisting of a C-N coupling-, hydroamination- followed by a final, ring-closing C-H arylation step. Products were isolated in moderate to good yields. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Product Details of 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The core structure is a part of various pharmaceutical substances and natural products. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Product Details of 6287-82-7
