A convenient one-pot synthesis of <i>N</i>-substituted amidoximes and their application toward 1,2,4-oxadiazol-5-ones
The first direct one-pot approach for the synthesis of N-substituted amidoximes from secondary amides or the intermediate amides has been developed. Through the Ph3P–I2-mediated dehydrative condensation, a variety of N-aryl and N-alkyl amidoximes (R1(CNOH)NHR2, where R1 or R2 = aryl, alkyl, or benzyl) were readily afforded under mild conditions and short reaction times. The synthetic application of
