摘要
[1,2,3]Triazolo[1,5-a]pyridines functionalization with a trifluoromethyl group has been achieved for the first time using different synthetic strategies. Furthermore, these scaffolds have been employed as starting material in the synthesis of new 2,6-disubstituted pyridines containing the trifluoromethyl group, compounds that are not available using other methodologies. A fluorine-mediated triazolopyridine dimerisation is described, improving the previously known synthetic method. Preliminary studies focused on exploring triazolopyridines reactivity with electrophilic fluorine have revealed a new approach for the obtainment of imidazopyridines. (C) 2014 Elsevier B.V.
