摘要：
A method was developed for the synthesis of 3(5)-aryl-5(3)-pyrazolyl-1,2,4-oxadiazoles by acylation of amidoximes with acyl chlorides, followed by cyclization of pyrazolyl-O-acylamidoximes into the respective oxadiazoles. Nitration of these products was studied, in combination with nucleophilic substitution reactions in the obtained nitro derivatives.
