Abstract

The action of equimolar amounts of nitrous acid formed in situ on benzylcyclopropanes with electron-donor and electron-withdrawing substituents in the aromatic part of the substrate lead, at certain temperatures, exclusively to the insertion of an N=O fragment into the three-membered carbocycle with subsequent formation of a heterocyclic isoxazoline (4,5-dihydroisoxazole) system.
