Three‐in‐one: The nickel‐catalyzed asymmetric three‐component coupling of 1,3‐dienes, aldehydes, and a silylborane in the presence of a chiral phosphoroamidite ligand has been realized. The reaction proceeds by σ‐bond metathesis of an oxanickelacycle intermediate with the silylborane to afford the corresponding α‐chiral allylsilane derivative in a highly diastereo‐ and enantioselective manner.
