The ortho-selective C−Hborylation of a wide range of pyridines using pinacolborane was achieved through yttrium catalysis. Notably, the possible hydroboration side reaction was effectively suppressed by using the proper ligand/metal combination. The resultant 2-pyridyl boronates were subjected to further transformations such as a Suzuki–Miyaura coupling or the Chan–Lam amination.
