Sequential 1,3-Dipolar Cycloaddition of Nitrones to β-(2-Aminophenyl) α,β-Ynones and Cyclocondensation : A New Entry to the Isoxazolino[4,5-c]quinoline Ring / G. Abbiati, A. Arcadi, F. Marinelli, E.

Abstract:
The reaction of nitrones with β-(2-aminophenyl) α,β-ynones in toluene at reflux temperature affords cis-fused isoxazolinoquinolines in moderate-to-high yields. This sequential process takes place throughregioselective 1,3-diploar cycloaddition of the nitrone to the triple bond followed by condensation between the amino and carbonyl groups.
