Oxadiazoles heterocycles are presente in many structures with different pharmacological properties. However, the five-membered 1,2,4-oxadiazole heterocyclic ring has received considerable attention because of its unique bioisosteric properties and an unusually wide spectrum of biological activities. The literature reports a growing number of publications involving 1,2,4- oxadiazoles over recent years, which have been focused on its different pharmacological potentials. In this work, the synthesis, structural characterization and in silico evaluation of 1,2,4-oxadiazoles is described. (Z)-4-(fluoromethyl) benzamidoxime (3a) and (Z)-3-(trifluoromethoxy) benzamidoxime, starting products of interest, were
obtained in good yields (85% 3a e 93% 3b). On the other hand, 2-(3-aryl-1,2,4-oxadiazol-5-yl)-3,4- (methylenedioxy)-cinnamyl (6a-b) were obtained from methyl trans-3,4-(methylenedioxy)-cinnamate and arylamidoxime by irradiation in a focused microwave oven yields 88 and 65%, respectively. Additionally, the in silico study indicated that all synthesized compounds have a low risk of chronic toxicity and can be administered orally. In addition, there are strong physicochemical indications that support the likelihood of these compounds presenting anxiolytic, antidiabetic, antiemetic, and antiprotozoal activity.
