descrita. As estruturasedos intermediários e compostos finais foram determinadas a partir dos dados espectroscópicos. A facile and efficient synthesis of 3-aryl-5-[(1S)-t-butyloxycarbonyl-1-amino-(2S)-methyl-1-butyl)]-1,2,4-oxadiazoles 4a-f and 3-phenyl-5-[(1S)-t-butyloxycarbonyl-1-amino-1-ethyl]-1,2,4-oxadiazole 6 starting from arylamidoximes, N-t-Boc-L-isoleucine and N-t-Boc-L-alanine is decribed.The structures of the intermediates and final compounds have been deduced from spectroscopic data.
