general approach to construct β-, γ-, δ-, and ε- fluoroalkanes with good enantioselectivity is described. Different directing groups, such as benzyl, ketone, and sulfonyl, were shown to give good enantioselectivity under Suzuki cross-coupling conditions in the presence of a Ni catalyst and chiral diamine ligand. It includes the first examples of enantioselective synthesis of chiral fluorine-containing
