Synthesis of 4-Aryl Isoquinolinedione Derivatives by a Palladium-Catalyzed Coupling Reaction of Aryl Halides with Isoquinoline-1,3(2<i>H</i>,4<i>H</i>)-diones
The palladium-catalyzed cross-coupling reaction of arylhalides with isoquinoline-1,3(2H,4H)-diones for the synthesis of 4-aryl isoquinoline-1,3(2H,4H)-diones was developed. The reaction conditions exhibit remarkable compatibility with various arylhalides and isoquinoline-1,3(2H,4H)-diones, and the product could be conveniently transformed to 4-aryl tetrahydroisoquinolines. (±) Dichlorofensine was

AbstractA series of 1,3,4(2H)‐isoquinolinetriones have been found to be fast‐acting post‐emergence herbicides, producing symptoms of desiccation. These redox‐active compounds are very potent stimulators of the light‐dependent consumption of oxygen at photosystem I in isolated chloroplasts. Pulse radiolysis studies on 2‐ethyl‐1,3,4(2H)‐isoquinolinetrione have shown it to have free‐radical properties which could enhance the generation of superoxide radicals in plants. Electrochemical studies further support a redox mediator mode of action for the series. The compounds were found to be unstable towards hydrolysis, and this was considered to be a major factor limiting the overall herbicidal effects. Other parameters, related to uptake and/or translocation, which may limit the full expression of the herbicidal activity of certain compounds, are discussed.
