Abstract
2-Substituted naptho[2,1-b]pyran-3-ones have been synthesised by a novel one-pot method which involves cyclocondensation of 2-hydroxy-1-naphthaldehyde with 5-methyl-1,3,4-thiadiazol-2-ylsulfanyl-, 1H-1,2,3,4-tetrazol-1-yl-, 1H-indol-3-yl-, quinolin-8-yloxy- and 4-methylquinolin-2-yloxy-acetic acids in the presence of DCC–DMSO using microwaves as well as conventional heating.
