We report a divergent synthesis of CF3-substituted fused skeletons based on precise control of the activation site through the selection of acid catalysts. When trifluoromethyl ketones with an ortho-phenethyl ether group were treated with a catalytic amount of Sc(OTf)3, a hydrideshift triggered C(sp3)–Hbondfunctionalization proceeded to give CF3-substituted isochromene derivatives by selective activation

A synthetic strategy for forming multisubstituted naphthalenes based on hydride shift mediated C(sp3)–H bond functionalization was developed. This strategy consists of three successive transformations: (1) an intramolecular hydride shift mediated C(sp3)–H bond functionalization; (2) a decarboxylative fragmentation; and (3) an oxidation reaction. When benzylidene malonates having a 2-alkoxyethyl group
