Six new phosphite ligands were prepared and their efficiency as chiral ligands was investigated in the copper‐catalyzed asymmetric conjugate addition of dimethylzinc to diethyl 3‐phenylpropylidenmalonate (5), affording the addition product with ees up to 74%. Moreover, a simple and straightforward route to floralfragrances Phenoxanol, Citralis, and Nitrile Citralis in optically active form through
