Expeditious Construction of a Carbobicyclic Skeleton via sp3-C−H Functionalization: Hydride Shift from an Aliphatic Tertiary Position in an Internal Redox Process

Described herein is the first example of an aliphatic, nonbenzylic hydride shift/cyclization sequence that contains two types of novel sp(3)-C-H functionalization: (1) construction of a tetraline skeleton via [1,5]-hydride shift/cyclization and (2) [1,6]-hydride shift/cyclization to form a five-membered ring (indane derivatives).
