Abstract
An efficient one-pot synthesis of perfluoroalkylated ring-fused 2-pyridones by three-component reaction of diamine, ketene dithioacetal, and methyl 2-perfluoroalkynoate in EtOH is reported. This protocol has the advantages of easiness, higher yields, and shorter reaction time. A plausible mechanism for this type of cyclization is proposed.
