Cycloaddition dipolaire-1,3 des arylnitriloxydes sur les dihydro-1,2 quinoleines n-substituees

The 1,3-dipolar cycloaddition reaction of arylnitrile oxideson 1,2- dihydroquinolines gives two adducts if the nitrogen atom of the dipolarphile carries benzoyl group. On the other hand the reaction provides only one adduct in the N-substituentis benzyl group. The structure of the cycloadducts has been established by spectroscopic and chemical method.
