, p. 763 - 773 (2007/10/02)
Reactions of hydroxylamine with 4'-substituted flavones have been investigated.Formation of oxime flavone and isoxazole for R = -OCH3, -CH3, -Cl and only isoxazole for R = -OH has been stated, whereas for R = -NO2 formation of an intermediate product of opening γ-pyrone ring and both isomeric isoxazoles has been observed.
CHALCONE OXIMES. PART V. REACTION OF HYDROXYLAMINE WITH 4-SUBSTITUTED 2'-HYDROXYCHALCONES
Witczak, Zbigniew,Krolikowska, Maria
, p. 89 - 100 (2007/10/02)
The reactions of hydroxylamine with 4-substituted 2'-hydroxychalcones have been investigated.Formation of products of 1,2 addition and simultaneous 1,4 and 1,2 addition for R = -CH3, -Cl have been established.Products of 1,2 addition for R = -OCH3 and of
