A palladium-catalyzed asym. reductive Heck reaction of unactivated aliphatic alkenes, with eliminable β-hydrogen atoms, was realized for the first time. A series of optically active bicyclo[3.2.1]octanes bearing chiral quaternary and tertiary carbon stereocenters were obtained in good yields with excellent enantioselectivities, exhibited good functional-group tolerance and scalability. Moreover, deuterated optically active bicyclo[3.2.1]octanes were also obtained in high efficiency.
