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.
据报道,通过二胺,乙烯酮二硫缩醛和2-全氟炔酸甲酯在EtOH中的三组分反应,可以有效地一锅合成全氟烷基化的环稠合2-吡啶酮。该方案具有容易,产率高和反应时间短的优点。对于这种类型的环化,提出了一种合理的机制。
