Abstract: ABSTRACT Three novel sets of coumarin-based derivatives viz. Schiff’s bases from 2-oxo-2 h-chromene-3-carboxylic acid with terminal alkyl benzene and alkyl biphenyl cores, methyl- or ethyl-group-derived coumarin esters from 7-hydroxy-4-methyl-2 h-chromen-2-one, and ethyl-7-hydroxy-2-oxo-2 h-chromene-3-carboxylate were synthesised and characterised for… read more here.

Abstract: A new series of N′-{[(4-methyl/phenyl-5-phenyl-4H-1,2,4-triazol-3-yl)thio]acetyl}-2-oxo-2H-chromene-3-carbohydrazides was synthesised via the reaction of 2-[(4-methyl/phenyl-5-phenyl-4H-1,2,4-triazol-3-yl)thio]acetohydrazides and 3-(1H-benzotriazol-1-ylcarbonyl)-2H-chromen-2-ones in good yields. read more here.
