Abstract N-Substituted 2-iminocoumarins are formed on reacting 2-iminocoumarin-3-carboxamide with anthranilic acid, methyl anthranilate, anthranilamide, and anthranilonotrile. Depending on the reaction conditions these recyclize into the corresponding 3-substituted coumarins or are hydrolyzed to coumarin-3-carboxamide. An alternative synthesis of some of the compounds has been effected.
