The reaction of various ethyl 3-[[2-(1-hydroxyiminoalkyl)phenyl]carbamoyl]acrylates (2) with electron deficient olefins proceeds via a sequential dipole formation, dipolar cycloaddition sequence to furnish the tetrahydro ...
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 ...
