A metal-free oxidative cycloaddition reaction of substituted benzamides and alkynes has been developed for the synthesis of isoquinolones by using bis(trifluoracetoxy)iodobenzene (PIFA) and trifluoroacetic acid (TFA). Under mild conditions, a wide variety of isoquinolones were conveniently prepared via oxidative annulation of simple N-methoxybenzamide and diarylacetylene or aryl/alkyl acetylene derivatives
通过使用双(三氟乙酰氧基)碘苯(PIFA)和三氟乙酸(TFA),已开发了取代苯甲酰胺和炔烃的无金属氧化环加成反应,用于合成异喹诺酮。在温和的条件下,可通过简单的N-甲氧基苯甲酰胺和二芳基乙炔或芳基/烷基乙炔衍生物的氧化环化反应方便地制备各种异喹诺酮,收率高达87%。
