Abstract: The reaction of acenaphthylene-1,2-dione with chiral cyclic secondary a-amino acids viz. l-proline gives rise to the intermediate azomethine ylide which has been trapped by acetylenic and ethylenic dipolarophiles to produce bridgehead bicyclic cycloadducts. The stereoselectivity of these cycloadditions have been ascertained by semiempirical calculations. The newly synthesized spiroazabicyclic compounds have been characterized by elemental analyses and spectral techniques (IR, 1H NMR, 13C NMR and Mass).
