Three-Component Synthesis of New C3-Substituted 5,6-Dihydropyrrolo[2,1-a]isoquinolines
New C3-substituted 5,6-dihydropyrrolo[2,1-a]isoquinolines have been synthesized via three-component domino reaction of 1-aroyl-3,4-dihydroisoquinolines, dimethyl acetylenedicarboxylate, and CH acids in anhydrous acetonitrile under microwave irradiation at 130°C.
