Highlight
Incredibly electrophilic keteniminium ions generated in situ were employed as powerful intermediates for cascade [1,5]-hydride transfer/cyclization, via which inert benzylic and non-benzylic C(sp3)–H bonds without a directing group were directly functionalized to furnish complex polycycles in a single operation.
