Microwave induced reaction between aminoacids 1a-c and phthalic anhydr
ide 2 gave N-substituted phthalimide acids, 3a-c. The condensation of
the latter with benzamidoxime furnished oxadiazoles 4a-c. M.O. calcula
tions of 4a-c using semi-empirical AM1 method provided electronic para
meters and other details.
