  A selective copper(I)-catalyzed benzylic C(sp3)–H geminal difunctionalization reaction of a benzylic-type sp3 carbon was developed. This novel strategy allowed simultaneous introduction of amide and hydroxyl group in a highly selective and efficient way via successive oxidative intramolecular amidation and hydroxylation. This method was also applied to the synthesis of 3-hydroxy-2,3-dihydro-1H-pyrrolo[3
