Palladium-Catalyzed Domino Cyclization and C-H Amination of 1,7-Enynes Toward N-containing Fused Quinolin-2(1H)-ones

A novel palladium-catalyzed domino radical cyclization and C–H amination of 1,7-enynes has been developed for the rapid establishment of N-containing fused quinolin-2(1 H )-one scaffolds.
