Nitrogen containing heterocycles from aldoximes; a one-pot route to isoxazolobenzodiazepinones, n-substituted and n-unsubstituted isoxazoloquinolinones
(Royal Society of Chemistry (RSC), 1998-01-01)
The aldoximes 1 in the presence of electron poor olefins react to form either the 5,6,7-tricyclic isoxazolobenzodiazepinone 3 or the 5,6,6-tricyclic isoxazoloquinolinone 5 ring skeleton, In each case the ring system formed ...
Steric control of reactivity: formation of oximes, benzodiazepinone n-oxides and isoxazoloquinolinones
(Royal Society of Chemistry (RSC), 1998-01-01)
Reaction of the alkenyl carbonyl compounds 1 with hydroxylamine can lead to the formation of the oximes 2, the benzodiazepinone N-oxides 3 or the isoxazoloquinolinones 5. The product(s) of reaction are shown to depend on ...
