An I2-promoted one-pot protocol was proposed for the synthesis of 2-aryl-3-(pyridine-2-ylamino)imidazo[1,2-a]pyridines from aromatic ketones and 2-aminopyridines. The present reaction proceeded well in the presence of I2 in DMSO, and it avoided the requirement of any metal, base, and ligand.
提出了一种I 2促进的一锅操作规程,用于从芳族酮和2-氨基吡啶合成2-芳基-3-(吡啶-2-基氨基)咪唑并[1,2- a ]吡啶。本反应在DMSO中存在I 2的情况下进行得很好,并且避免了对任何金属,碱和配体的需要。
