The synthesis of 3-(3-aryl-1,2,4-oxadiazol-5-yl)propionicacids from arylamidoximes and succinic anhydride under focused microwave irradiation conditions is described. The new synthetic method furnished the desired products in 2-3 min and good yields. Furthermore, the previously complicated purification procedure has been simplified in a manner which is quick, eco-friendly and cost-effective. Larvicidal

(HTE) has emerged as an important tool in drug discovery, providing a platform for preparing large compound libraries and enabling swift reaction screening over wide-ranging conditions. Recent advances in automated high-density, material-sparing HTE have necessitated the development of rapid analytics with sensitivity and resolution sufficient to identify products and/or assess reaction performance in

Seven 3,5-disubstituted oxadiazole derivatives, 3a-g, have been prepared by direct condensation of appropriate benzamidoxime with succinic anhydride. Spectroscopic properties, especially uv, ir and massspectra confirmed the cyclic 1,2,4-oxadiazole structure. No ring-opened intermediate or side product could be observed. The 1H-nmr assignments of the two CH2 groups were unequivocally made by acid-
