The reaction of 4-fluoro-3-nitrobenzylidenemalononitrile (3) with piperidine and 1-naphthol yields the addition-elimination product (9) rather than the expected naphthopyran (7).This reaction is extended to produce other 3,4-disubstituted benzylidenemalononitriles (10)-(13).These compounds are then reacted with 1-naphthol and 4-methylmorpholine producing the naphthopyrans (14)-(17).
