Abstract:

N-(pyridine-2-yl)amides were synthesized in one step with benzyl alcohols and 2-aminopyridines in copper-catalyzed aerobic conditions by air bubbling method. The mechanism study demonstrated that benzaldehydes were formed in situ from benzyl alcohols under aerobic conditions and acted as coupling partners to react with 2-aminopyridines to synthesize amides. The bioactivity study showed that the synthesized products possessed certain antibacterial activity. This reaction features high efficiency and functional group tolerance. Moreover, no additives were used in the reaction and this method utilized oxygen from the air as an ideal oxidant with the virtue of economy and green.
