Gold(III)-catalyzed tandem reaction of O-arylhydroxylamines with 1,3-dicarbonyl compounds: highly selective synthesis of 3-carbonylated benzofuran derivatives.
A highly regioselective protocol for the synthesis of 3-carbonylated benzofuran derivatives has been developed involving the gold(III)-catalyzed tandem condensation/rearrangement/cyclization reaction of O-arylhydroxylamines with 1,3-dicarbonyl compounds.
