Abstract
The reaction of methyl nitrone, a derivative of 3-imidazoline 3-oxide, with methyl nitrate in the presence of PhLi results in β-nitronitrone. The tnteraction of the latter with electrophiles involves, as a rule, the methylene group. Nitrile oxide, which is an 3-imidazoline 3-oxide derivative, has been generated by thermolysis ofgem-nitrooxime. This easily dimerizes to furoxan or undergoes regioselective 1,3-dipolar cycloaddition with alkenes.
