An efficient, metal-free method for the synthesis of 3-formyl imidazo[1,2-a]pyridines is reported. The method utilises commercially available substrates and features a broad substrate scope. The intermediate enamine was isolated and a plausible reaction mechanism proposed.

The heterogeneous annulation between 2-aminopyridines and propiolaldehydes was achieved in CH2Cl2 at 25 °C in the presence of 3 mol% of MCM-41-immobilised phosphine gold(I) complex (MCM-41-PPh3-AuCl) and AgSbF6

A novel and efficient iron(III)-catalyzed C3-formylation reaction of imidazo[1,2-a]pyridine in an oxygen atmosphere has been developed. The method is conducted in dimethyl sulfoxide (DMSO), which serves as both the carbonyl carbon source and solvent, in the presence of acetic acid to directly generate structurally diverse 3-formylimidazo[1,2-a]pyridine derivatives in moderate to good yields.
