The cycloaddition reactions of three cyclic imidateesters, 2-ethoxypyrrolin-5-one (6), 2-ethoxyisoindol-3-one (7) and 2-ethoxy-1H-indol-3-one (8) with various 1,3-dipoles were investigated. Dipolarophile 6 added only to nitrile oxides; 8 added to nitrile oxides and to nitrilimines; 7 failed to undergo cycloaddition reactions with either nitrile oxides or nitrilimines.
