Domino N2-Extrusion-Cyclization of Alkynylarylketone Derivatives for the Synthesis of Indoloquinolines and Carbocycle-Fused Quinolines

New synthetic approaches for the synthesis of indoloquinolines and carbocycle-fused quinolines have been developed employing alkynylketone substrates. These synthetic transformations involved the application of N2-extrusion of azido complexes as a key step to generate carbodiimidium ion and nitrilium ion in situ, which further cyclized intramolecularly with alkyne via a domino process to provide indoloquinolines and carbocycle-fused quinolines, respectively, in moderate to good yields.

4 + 1 Radical Annulations with Isonitriles: A Simple Route to Cyclopenta-Fused Quinolines

Sunlamp irradiation of 1-substituted 5-iodo-1-pentynes, 5 equiv of phenyl isocyanide, and 1.5 equiv of hexamethylditin in tert-butylbenzene (0.01-0.025 M) at 150°C produces 9-substituted 2,3-dihydro-1H-cyclopenta[b]quinolines in 36-70% yields. A mechanist
