RESUMO
Uma síntese fácil e eficiente de 3-aril-5[(1S)-t-butiloxicarbonil-1-amino-( 2S)-metil-1-butil)]-1,2,4-oxadiazóis 4a-f e 3-fenil-5-[(1S)-t-butiloxicarbonil-1-amino-1-etil]-1,2,4-oxadiazol 6 partindo de arilamidoximas, N-t-Boc-L-isoleucina e N-t-Boc-L-alanina é descrita. As estruturasedos intermediários e compostos finais foram determinadas a partir dos dados espectroscópicos.
