摘要

2-Naphthol and naphthalenediols react with methylenemalononitrile, generated in situ from reaction of formaldehyde and malononitrile, to yield naphthopyrans and naphthodipyrans. 5- Hydroxynaphtho [2, 1-b] pyrans reacted further with methylenemalononitrile to yield naphthodipyrans. The reaction of methylenemalononitrile with 4-methylcoumarin-3- carbonitrile afforded benzopyrano [4, 3-h] quinoline. 6-Cyanomethyl-3- ...
