Synthesis of coumarin-tagged 1,3,4 oxadiazole conjugates

C oumarins are an important class of heterocyclic compounds with natural and synthetic origins. It has a unique benzo-
α-pyrone which has demonstrated proliferative biological activity. Similarly, the 1,3,4-oxadiazole heterocycles exhibit
remarkable pharmacological and biological properties, e.g., antibacterial, anti-viral, anti-cancer, anti-coagulation and anti-
inflammatory activities. The 1,3,4-oxadiazole ring is highly lipophilic thus improving drug permeability across cell membranes,
ensuring the drug reaches the biological target. Both classes of compounds form valuable leads in drug discovery i.e. coumarin
fused 1,3,4-oxadiazole and their derivatives. Molecular hybridization techniques have been used in drug design and discovery.
The method involves the combination of two or more bioactive pharmacophores to generate a single molecular scaffold with
improved affinity and bioactivity, in comparison to the parent molecules. Accordingly, a series of novel 7-((5-mercapto-1,3,4-
oxadiazol-2-yl)methoxy)-4,5-dimethyl-2H-chromen-2-one derivatives was synthesized. Using commercially available orcinol
as the starting material, the key intermediate 7-((5-mercapto-1,3,4-oxadiazol-2-yl)methoxy)-4,5-dimethyl-2H-chromen-2-
one was synthesized in four steps: condensation; esterification; hydrazidation and; cyclization; followed by alkylation and
benzylation.
