Condensation of 6-R-3-formylchromones (I) with 3,3-dimethyl-1,3-cyclohexanedione (II), 1,3-indandione (III), 1,2e-biindenylidene-3,1e,3e-trione (bindone, IV), 2-oxo-1,4-benzothiazine (V) and 3-oxo-2,3-dihydro-1-thia-3a,8-diazacyclopent[a]indene (VI) by the "classical" method, as well as condensation in a microwave oven, has been studied. Some subsequent reactions of these products are described.
