excellent yields. A one‐pot, unsymmetrical, twofold C−H functionalization involving intramolecular C−C and intermolecular C−C/C−N bond formations is successfully demonstrated by using a single set of catalytic reaction conditions, which is unprecedented thus far. A novel isoquinolone‐bearing dihydrobenzofuran is constructed through an unsymmetrical twofold C−H functionalization.

example of Cp*Co(III)-catalyzed intramolecular hydroarylation of allyl aryl ethers using an amide directing group for the preparation of 3,3-disubstituted dihydrobenzofurans in high yields is described. The reaction of the unactivated alkene is completely selective for the formation of the quaternary center, allowing different substitution patterns on the aromatic ring and the alkene. The cyclization
