Scientists from the Indian Institute of Technology have investigated the effect of visible light on theHantzsch reaction– a method by which to produce dihydropyridines which have found merit for cardiovascular disease treatment.By doing so,they were able to develop a photocatalytic-based methodology for producing 2-arylpyridines.Whilst such compounds are popular in medicinal 新利手机客户端chemistry and supramolecular coordination chemistry fields,their synthesis can be troublesome.
Armed with a catalytic amount of [Ru(bpy)3]2+and a household compact fluorescent lamp,the team synthesised the 2-arylpyridine compound through photocatalytic oxidation of the 1,2-dihydropyridine Hantzsch product.
