Modular syntheses of 1,4,5-trisubstituted 1,2,3-triazoles by a one-pot three-step procedure: toward bio-inspired monomers

摘要

Synthesis of 1,4,5-trisubstituted 1H-1,2,3-triazoles is reported by means of a transition metal-catalyzed arylation of 1-substituted-4-(2-bromoethyl)triazoles. The process which consists of one-pot three-step procedure allows a direct access to 1,5-disubstituted-4-(2-hydroxyethyl)triazoles and is suitable as an alternative methodology in the preparation of highly substituted triazoles in view of polymer chemistry
