The choice of scaffold and tether has a marked influence on the enantiomeric excesses obtained in Pd‐catalyzed asymmetric allylic alkylations, such as the cyclization of the bisurethane 1 to the oxazolidin‐2‐one 2 [Eq. (1); Ts= p ‐toluenesulfonate], performed with polymer‐supported chiral catalysts. The best results were obtained by using an ArgoGel resin, an amide tether, and a pyrrolidine scaffold.
