Abstract :
The reaction of dibenzoylacetylene with 4-alkylaminocoumarins in THF/H2O (50:50) leads to the formation of
4-(alkylamino)-3-(1,4-dioxo-1,4-diphenylbut-2-en-2-yl)-2H-chromen-2-one derivatives in good yields. The cyclized products
2-hydroxy-1-alkyl-3-(2-oxo-2-phenylethylidene)-2-phenyl-2,3-dihydrochromeno [4,3-b] pyrrol-4(1H)-ones were formed in good yields,
when the reaction was carried-out in DMSO.
