experimental part, p. 7903 - 7912 (2009/09/06)
A new procedure for the synthesis of 4.5-dihydroisoxazoles by condensation of primary nitro compounds with olefins by using a copper/base catalytic system is described. The catalytic effect of copper(II) salts is evidenced by comparison of the reaction ra

Primary aliphatic nitro compounds condense with substituted alkenes to give 4,5-dihydroisoxazoles under copper(II) acetate catalysis in the presence of tertiary amines. Apparently nitrile oxides are not intermediates, as no furoxans are detected in these
Synthesis of some isoxazolines and evaluation of carbon-13 NMR substituent parameters for 5-methyl substitution
Nagarajan, A.,Pillay, M. Krishna
, p. 938 - 941 (2007/10/02)
Some isoxazolines substituted at C-5 with phenyl and methoxycarbonyl groups have been synthesised and characterised.Carbon-13 NMR methyl substituent parameters for methyl substitution at C-5 carbon in these compounds have been evaluated.

Three nitrile oxides (MeOCOCN->O, PhCN->O, and EtCN->O) were effectively generated in situ by dehydration of the corresponding primary nitro compounds (RCH2NO2) with PhSO2Cl or ClCOOEt in the presence of triethylamine.Various cycloadducts were prepared by the reaction of them with dipolarophiles.Some advantages of these methods are described in comparison with other known methods.
