New highly efficient method for the cyclization of acylamidoximes in the presence of diazabicycloundecene was developed and incorporated into a general and practical one-pot synthesis of 1,2,4-oxadiazoles (11 examples, 85-97% yields).

O-Acyl derivatives of benzamidoxime, 1a, and tolylamidoximes, 1b-g, have been prepared.Out of seven compounds, four (viz., 1b,c,e,f) are new.The structure of these compounds were determined with the aid of UV, IR and NMR spectra.Molecular orbital calculations have been performed using the CNDO/2 method in order to obtain more insight into the configuration and conformation of these molecules.Our results support the view that Z configuration at the C=N bond and the ap conformation at the N-O bond in the O-acyl derivatives are the most stable ones.
