p‐TsOH‐mediated, Versatile, and Efficient Approach for the Synthesis of Triazolyl‐Carbazoles from Nitrovinylcarbazoles and Azide via 1, 3‐Dipolar Cycloaddition

An efficient method for the synthesis of N‐alkylated 3‐(1‐benzyl‐1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazoles (5, 6, 7, 8, 9, 10) and 9‐ethyl‐3,6‐di(1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazole (13) has been developed from nitroolefines. The effects of catalyst and solvent on these reactions have been investigated...

Description
Summary:An efficient method for the synthesis of N‐alkylated 3‐(1‐benzyl‐1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazoles (5, 6, 7, 8, 9, 10) and 9‐ethyl‐3,6‐di(1H‐1,2,3‐triazole‐4‐yl)‐9H‐carbazole (13) has been developed from nitroolefines. The effects of catalyst and solvent on these reactions have been investigated. p‐TsOH‐THF was found to be the best system for this reaction. Various triazolyl‐carbazoles were prepared in good to excellent yields.
