Isoxazoline N-oxides

The thermal decomposition of the silver salt of dinitrophenylmethane in the presence of an alkene produced an isoxazoline AT-oxide via a proposed arylnitrocarbene (80JOC4158), 

Generalized methods of preparation indude the reaction of j8-keto esters (or amides) with hydroxylamine, a-alkynic and a,/3-unsaturated esters (or amides) with hydroxylamine (real or generated in situ), hydroxylamine and nitrile oxides, and /3-keto and a-alkynic nitriles with hydroxylamine (62HC(i7)l,pp.3,7 .
