Özet
By using the microwave technology, a new protocol has been developed for the synthesis of new coumarin derivatives including 1,2,4-triazol-3-one skeleton. This protocol proves to be efficient and environmentally friendly in terms of easy work-up and good yields. All newly synthesized compounds were screened for their antimicrobial activity and lipase inhibition. Most of the compounds were found to be effective on Escherichia coli. N'-{[4-Amino-3-(2-bromobenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}-6-bromo-2-oxo-2Hchromene-3-carbohydrazide and N'-{[4-amino-3-(3,4-dichlorobenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}-6-bromo-2-oxo-2H-chromene-3-carbohydrazide had a good effect on lipase inhibition.
