Synthesis of novel triazolopyridylboronic acids and esters. Study of potential application to Suzuki-type reactions

This paper describes a general method for the synthesis of novel 1,2,3]triazolo1,5-a]pyridylboronic acids and esters, and the first results on Suzuki cross-coupling reactions with these new compounds and 1,2,3]triazolo5,1-a]isoquinolylboronic acid, reacting with a variety of aryl halides as a route to 7-aryltriazolopyridines and 5-aryltriazoloisoquinolines.
