A new efficient protocol for the synthesis of isochromeno[3,4-b]-, [4,3-a]-, -[4,3-b]-, and -[3,4-c]carbazolones has been successfully established via palladium-catalyzed intramolecular ortho-arylation of C-H bond under ligand-free conditions.
在无配体条件下,通过钯催化 C-H 键的分子内正芳香化作用,成功建立了合成异色烯并[3,4-b]-、[4,3-a]-、-[4,3-b]-和-[3,4-c]咔唑酮的高效新方案。
