The first example of intramolecular cycloaddition of carbene-derived azomethine ylides in a domino reaction of difluorocarbene with Schiff bases

Domino reactions of difluorocarbene with Schiff bases containing a tethered olefinic or acetylenic dipolarophile moiety involve intramolecular 1,3-dipolar cycloaddition of iminiodifluoromethanides and yield chromeno[4,3- b]pyrrole derivatives. Graphic
