摘要
Palladium-catalysed competitive three-component C-H functionalisation reactions and cascade coupling ring-closing reactions of quinones with iodophenols in dihaloalkanes are described. During initial attempts to conduct C-H functionalisation reactions of quinones with iodophenols in dihaloalkanes, surprisingly a three-component C-H functionalisation reaction was discovered. Furthermore, as the reaction of chloroquinones with iodophenols was in progress, another surprising cascade coupling with ring closure was achieved. This provided an efficient single-step synthesis of naphtho[2,3-b] benzofuran-6,11-diones.
