Microwave assisted synthesis of 2-amino-6-methoxy-4H-benzo[h]chromene derivatives El-Agrody, Ahmed Mohamed Al-Dies, Al-Anood Mohamed Fouda, Ahmed Mahmoud Benzochromenes Pyran derivatives Microwave synthesis 4-Methoxy-1-naphthol α-Cyanocinnamonitriles Ethyl α-cyanocinnamates A convenient and efficient method using microwave assisted synthesis of 4H-benzo[h]chromenes (7 and 8), by the reaction of 4-methoxy-1-naphthol (1) with a mixture of aromatic aldehydes (2) and malononitrile (3) or ethyl cyanoacetate (5) and also, by the reaction of 4-methoxy-1-naphthol (1) with α-cyanocinnamonitriles (4) or ethyl α-cyanocinnamates (6) in ethanolic piperidine solution was examined. Structures of the newly synthesized compounds were established on the basis of spectral data, IR, 1H NMR, 13C NMR, 13C NMR-DEPT and MS data.
