Copper-Catalyzed Intramolecular Carbocyclization/1,2-Migration Reaction of Allenols To Access Substituted 2-Sulfonyl Carbazoles | Aslam Shaikh🚀 Publication Alert from ACS Lab group,@ Indian Institute of Technology, Ropar! Our research work entitled “Copper-Catalyzed Intramolecular Carbocyclization/1,2-Migration Reaction of Allenols To Access Substituted 2‑Sulfonyl Carbazoles” has been accepted for publication in Organic Letters, American Chemical Society. Read the full article here- https://lnkd.in/gjkDZMUc Congratulations to Puja Singh and Pooja Nain on this fabulous work! We presented a copper-catalyzed intramolecular cascade carbocyclization/1,2-migration of C-2 indolyl-allenol to construct the library of 2-sulfonyl carbazoles, which possess considerable biological significance. This modular protocol is operationally simple, exhibiting a broad substrate scope with consistently high yields. Additionally, gram-scale synthesis, product diversification of 2-sulfonyl carbazoles, and DFT studies of the catalytic cycle have been performed. Overall, this study unfolds a new strategy for the one-pot synthesis of sulfonyl carbazoles, which holds significance in medicinal and material chemistry. Special thanks to Dr. Manoj Mane for DFT studies. ACS group members Rahul Thombare, Nand Lal, Kavneet Kaur, and Sanjay Singh Bisht. Follow the ACS group page for the latest update. We are grateful to the Indian Institute of Technology, Ropar, Anusandhan National Research Foundation (ANRF), ANRF-Partnerships for Accelerated Innovation and Research (PAIR), and DREAMS Project for financial support. Always thankful to the Department of Chemistry IIT Ropar.
