ChemInform Abstract: Synthesis and Characterization of New 1,3,4‐Oxadiazolines.

The synthesis and biological activities of 3-acyl- 2,3-dihydro-1,3,4-oxadiazole/ 3-acyl-1,3,4-oxadiazoline derivatives obtained from hydrazide-hydrazones

“…However the hydrolytic stability of hydrazones are depend on the structure of the substituent (1). 2,3-Dihydro-1,3,4-oxadiazol derivatives are stable structures (40) and obtained from intramoleculer cyclization of hydrazide hydrazones by acid anhydrides or acylchlorides (1,(41)(42)(43)(44)(45)(46). In 1953, Yale and co-workers (41) reported the publication of related compounds.…”
