An efficient copper-catalyzed method for the synthesis of quinolinones,
pyridinones, and heteroannulated pyridinones via cascade reactions
of substituted 2-iodo-, 2-bromo-, and 2-chlorobenzocarbonyls with
2-arylacetamides is reported. The protocol works well for the reaction
of most of the 2-iodo-, 2-bromo- and 2-chlorobenzocarbonyls with
2-arylacetamides.
