One-Pot Sonogashira Coupling–Cyclization toward Regioselective Synthesis of Benzosultams Sudarshan Debnath Shovan Mondal 10.1021/acs.joc.5b00274.s002 https://acs.figshare.com/articles/dataset/One_Pot_Sonogashira_Coupling_Cyclization_toward_Regioselective_Synthesis_of_Benzosultams/2175577 A one-pot method for the Sonogashira coupling and cyclization of 2-bromobenzenesulfonamides and terminal alkynes is presented. This method allows access to a variety of substituted benzosultams regioselectively in excellent yields. The reasons for regioselectivity are interpreted through density functional theory (DFT) studies. 2015-04-17 00:00:00 Regioselective Synthesis terminal alkynes yield access variety cyclization BenzosultamsA method regioselectivity DFT benzosultams regioselectively density bromobenzenesulfonamide Sonogashira
