The non‐cross‐linked polystyrene (NCPS)‐supported 2‐imidazolidinone chiral auxiliary, based on a new anchoring strategy, afforded excellent diastereocontrol and yield in asymmetric alkylation reactions. The cleavage of this soluble, polymer‐supported chiral auxiliary 8 produced highly optical pure carboxylic acids and strong polymer recovery.
