A palladium-catalyzed alkyl C–H borylation with bromide as a tracelessdirectinggroup is described, providing a convenient approach to access alkyl boronates bearing a β-all-carbon quaternary stereocenter. The protocol features a broad substrate scope, excellent site selectivity, and good functional group tolerance.
