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-hydrazonesKeywords: 2 , 3-dihydro-1 , 3 , 4-oxadiazole , 3-acyl-1 , 3 , 4-oxadiazoline , hydrazide hydrazones , biological activities Abstract: In this review, the synthesis and biological activities of 3-acyl-2,3-dihydro-1,3,4- oxadiazole derivatives are reported. Synthesis of 1,3,4-oxadiazolines via carboxylic acid hydrazide-hydrazones by using acetic anhydride or other cyclization agents establishes the peculiar basis of our work.
