A variety of acyclic chiral dienes were synthesized in a single step via palladium(0)‐catalyzed asymmetric allylic and homoallylic CH diamination of terminalolefins. The applications of such simple dienes as steering ligands for rhodium(I)‐catalyzed asymmetric 1,4‐additions afforded the corresponding adducts in excellent yields and up to 85% ee.
