The influence of oxime stereochemistry in the generation of nitrones from ω-alkenyloximes by cyclization or 1,2-prototropy
(Royal Society of Chemistry (RSC), 1998-01-01)
Thermally induced cyclization of the anti-alkenyl oximes E-7a,b and E-17a,b affords cyclic alpha-alkoxycarbonylnitrones 8 and the 6,7-bicyclic nitrones 18, respectively, The syn-oximes Z-7b and Z-17b react via an alternate ...
The synthesis of 1,2,7,11b-tetrahydroisoxazolo[2,3-d][1,4]benzodiazepin-6(5h)-ones and 1,3,3a,9b-tetrahydroisoxazolo[4,3-c]quinolin-4(5h)-ones
(Elsevier BV, 1995-10-01)
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 ...
Site selectivity in the addition of ketoximes to activated allenes and alkynes; n- versus o-alkylation
(Royal Society of Chemistry (RSC), 1999-01-01)
Reaction of ketoximes with methyl propiolate afforded geometrical isomers of the methyl 3-(hydroxyimino)propanoates 4 and of the O-vinyl oximes 5 as well as the 2-isoxazoline 6. With dimethyl penta-2,3-diendioate 8c reaction ...
