Sažetak
3-Acyl-4-hydroxy-2-oxo-2H-chromen derivatives 1a-d were condensed with (7-hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide 2, (4-methyl-2-oxo-2H-chromen-7-yloxy)-acetic acid hydrazide 3, and (7-hydrazinocarbonylmethoxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide 4, to give corresponding 3-alkyl-1-[2-(7-hydroxy-2-oxo-2H-chromeno-4-yl)-acetyl]-1H-chromeno[4, 3-c]pyrazole-4-one 5a-d, 3-alkyl-1-[2-(4-methyl-2-oxo-2H-chromeno-7-yloxy)-acetyl]-1H-chromeno[4, 3-c]pyrazole-4-one 6a-d, and 1-{;4-[(3-alkyl-1H-chromeno[4, 3-c]pyrazole-4-one-1-yl)-carbonylmethyl]-2-oxo-2H-chromen-7-yloxy-acetyl};-3-alkyl-1H-chromeno[4, 3-c]pyrazole-4-one 7a-d.
