Resumo

Previously unknown 6-acetyl-10-aryl-5-hydroxy-4-methyl-9,10-dihydropyrano[2,3-f]-chromene-2,8-diones were synthesized by multicomponent condensation of 6-acetyl-5,7-dihydroxy-4-methylchromen-2-one, aromatic aldehydes, and Meldrum´s acid. A fundamen-tal possibility of interconversion of substituted 6-acetyl-10-aryl-5-hydroxy-4-methyl-9,10-dihydropyrano[2,3-f]chromene-2,8-diones and methyl 3-(6-acetyl-5,7-dihydroxy-4-meth-yl-2-oxo-2H-chromen-8-yl)-3-arylpropionates was demonstrated.
