Amidoximes, IV. Dehydrogenation of a β-Hydroxylamino Amidoxime with azodicarboxylic Ester3-Hydroxylamino-2,3-diphenylpropionamide oxime (6), obtained from 2,3-diphenylacrylonitrile (5) by double addition of hydroxylamine, gave with the azodicarboxylate 2 via the β-nitroso-(isonitroso-)amide oxime 13a/13b 5-amono-3,4-diphenylisoxazole (7). From 13b 7 is formed by selective cyclisation (to 16) followed by selective elimination of hydroxylamine. Neither the structural isomer 3-aminoisoxazole 8 nor the 5-hydroxylamino derivative 15 were formed in this process.
Notes:
Das aus 2,3-Diphenylcrylonitril (5) durch doppelte Hydroxylamin-Addition erhaltene 3-Hydroxylamino-2,3-diphenylpropionamid-oxim (6) bildet mit dem Azodicarbonester 2 über das β-Nitroso-(isonitroso-)amidoxim 13a/13b 5-amino-3,4-diphenylisoxazol (7). 7-entsteht aus 13b durch selektive Cyclisierung (zu 16) und nachfolgende selektive Hydroxylamin-Eliminierung, Dieser Prozeß ergab weder das strukturisomere 3-Aminoisoxazol 8 noch das 5-Hydroxylamino-Derivat 15.
