1,3(2H,4H)-Dioxoisoquinoline-4-carboxamides, nuclear unsubstituted and substituted, are prepared by reacting the appropriate homophthalimide with potassium cyanate. Secondary carboxamides are prepared by reacting homophthalimide with appropriate isocyanates, and tertiary carboxamides are prepared by aminolysis of 4-carbalkoxy compounds, which are in turn prepared by alcoholysis of the corresponding 4-carboxanilides. Corresponding 5,6,7,8-tetrahydro compounds are similarly prepared. The various 2-substituted homophthalimides are prepared by reacting homophthalic acid with appropriate amine. The 4-carboxamides are anti-inflammatory agents.
