Title
Highly regioselective palladium-catalyzed direct cross-coupling of imidazo[1,2-a]pyridines with arylboronic acids
Abstract

•Pd-catalyzed cross-coupling of imidazo[1,2-a]pyridines with aryl boronic acids•It represents excellent C-3-regioselectivity direct arylation.•A new method for the formation of CC bonds to prepare imidazo[1,2-a]pyridines.

A highly regioselective method for the palladium-catalyzed direct cross-coupling of imidazo[1,2-a]pyridines with arylboronic acids has been developed by using O2 as oxidant. This process can be applied to a wide range of imidazo[1,2-a]pyridines and arylboronic acids with excellent C-3-regioselectivity. It provides a new way for developing CC bond-forming processes of multisubstituted imidazo[1,2-a]pyridines, which are common structural motifs in natural products and pharmaceuticals.
