(‐CH2OR) has been optimized for the palladium‐catalyzed asymmetric allylic amination. The optimal catalyst (R=CH3), depicting very high catalytic activity and broad scope applicability, has been further modified to include an ω‐alkynyloxy substituent of variable length for polymer supporting via click chemistry, and has been anchored onto slightly cross‐linked azidomethyl poly(styrene). The length of a polymethylene
