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