Abstract

A copper-catalyzed, three-component, one-pot, 1,3-dipole cycloaddition/oxidation has been developed to construct pyrrolo[2,1-a]isoquinolinoquinone derivatives, with environmentally friendly oxygen as the oxidant. The pyrrolo[2,1-a]isoquinolinoquinone products were obtained from naturally available tetrahydroisoquinolines, 1,4-naphthoquinones, and benzaldehydes in medium yields.
