Substrate scope of the sterospecific cross-coupling reaction. a Reaction conditions. b Scope of the Csp3 boronic acid coupling partner, (§: no improvement when using L2, *: branched on C3/branched on C2/linear (Supplementary Figure 5), #: L2 was used, L4 gave lower yields). c Scope of the bromide coupling partner. All reactions were performed in duplicate. Branched/linear ratios were determined by HPLC or GC analysis of the crude reaction using an authentic linear product standard. Yields were determined by isolation. Enantiospecificities were determined by chiral HPLC of the purified product
