Synthesis of designed new 1,3,4-oxadiazole functionalized pyrano 2,3-f chromene derivatives and their antimicrobial activities

Diethyl 2-(((4-methyl-2-oxo-2H-chromen-7-yl)oxy)methylene)malonate (2) was synthesized from coumarin 1 and diethyl ethoxymethylene malonate in ethanol, followed by cyclization in diphenyl ether to give chromene-9-carboxylate (3). Sugar hydrazones 5a-c were formed by reacting hydrazide 4 with D-galac...
