The neoflavonoids 7-hydroxy-5-methyl-4-(4'-methoxyphenyl)-3,4-dihydrocumarin (1), 5-hydroxy-7-methyl-4-(4'-methoxyphenyl)-3,4-dihydrocournarin (2), 5-methyl-7-O-coumaroyl-4-(4′-methoxyphenyl)-3,4-dihydrocoumarin (3), 5-hydroxy-4-(4'-methoxyphenyl)-a-pirano(6",5":7,8)-3,4-dihydrocoumarin (7), and 7-pentadecyl-4-(4'-methoxyphenyl)-3,4- dihydrocoumarin (8) were synthesized via the Aids-catalyzed condensation of 4-methoxycinnamic acid chloride with orcinol, 5,7-dihydroxycoumarin and hydrogenated cardanol. The compounds were characterized on the basis of their 1H- and C-NMR spectroscopic properties, including nOe difference spectroscopy. ©1997 Soc. Bras. Química.
