An iron(Ⅲ)-porphyrin-catalyzed cyclization of ketones with dimethyl sulfoxide (DMSO) and ammonium acetate for the synthesis of unsymmetrical and symmetrical pyridines by employing DMSO as C4 or C6 source has been developed. Various aryl ketone derivatives react readily with DMSO, producing the pyridines in yields of 30%~85%. This method uses non-noble metals and proceeds under mild reaction conditions with operational simplicity, which thus allows the expedient assembly of pyridines from readily available ketones. Based on the preliminary experiments, a plausible mechanism of this transformation is disclosed.
