RESUMO
An I2-induced 1,3-dipolar cycloaddition reaction has been developed for the synthesis of benzo[f]isoindole-1,3-dicarboxylates from quinones and N-substituted amino esters. The reaction proceeds in good to excellent yields in one step from 3 equiv of amino ester to react with the quinone structure. The utility of this transformation has been highlighted by its use for the construction of benzo[f]isoindole-1,3-dicarboxylates, which have been identified in natural products exhibiting important biological activities.
