Essassi, El Mokhtar,Salem, Moussa,Viallefont, Philippe

, p. 890 - 892 (2007/10/02)

The reaction of hydroxylamine with 4-phenyl-1,5-benzodiazepin 2-thiones(ones) 1-6 has been investigated.Depending upon the starting benzodiazepine either the 3-phenyl-5-N-(2-amino phenyl)amino isoxazoles 8, 10, 11 3-N-(2-aminophenylimino) 3-phenyl propionohydroxamic acid or 3-phenyl 5-isoxazolone 14 was obtained.The structure of compounds 8, 10, 11 have been unambiguously established by catalytic hydrogenation.A mechanism for this transposition has been suggested.
