An efficient and "green" protocol for the synthesis of 3-acylimidazo[1,2-a]pyridines through intramolecular oxidative α-amination of carbonyl compounds has been developed. The reaction proceeds smoothly utilizing I2 as a catalyst and H2O2 as an oxidant under neat condition with broad substrate scope. Several complex nitrogen-containing fused rings are conveniently constructed, which are not easy to access by traditional methods.

An efficient iron-catalyzed intermolecular aminooxygenation of 2-aminopyridines with a wide range of ynals has been developed. 3-Aroylimidazo[1,2-a]pyridines containing various functional groups are synthesized under the standard conditions. The transformation is conducted in simple conditions and forms products in good yields.
