Abstract

Motivated by the importance of developing new general methods toward multisubstituted 1,2,3-triazoles, we examined the feasibility of a direct Pd-catalyzed arylation reaction with aryl bromides: a method proved efficient in the highly regioselective C-3 arylation of indolizines. 14 It was found that C-5 arylation of 1,4-disubstituted 1,2,3-triazoles 1a−h in the presence of Pd catalyst and tetrabutylammonium acetate in NMP proceeded smoothly to provide C-5 ...
