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 ... -
Pyrimidine annelated heterocycles - synthesis and cycloaddition of the first pyrimido[1,4]diazepine n-oxides
(Royal Society of Chemistry (RSC), 2001-01-01)5-Formyl- and 5-acetyl-4-(alkenylamino)pyrimidines 5 have been prepared as precursors to novel pyrimido[1,4]diazepine N-oxides 3. In addition to cyclisation to the targeted dipoles the substrates 5 have also been observed ... -
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 ... -
Α-keto amides as precursors to heterocycles—generation and cycloaddition reactions of piperazin-5-one nitrones
(Royal Society of Chemistry (RSC), 2003-03-10)alpha-Keto amides 10a,b, formed from reaction of pyruvic or benzoylformic acid with allyl amine are found to present as single rotameric forms whilst their tertiary amido analogues 10c,d present as two rotamers in solution ...
