Polymer-supported chiral α-amino amides for the asymmetric addition of diethylzinc to aldehydes: Transforming an inactive homogeneous system into an efficient catalyst

- Immobilization of catalytic α-amino amide system onto a polymeric matrix.
- Increase in the enantioselectivity due to the pseudodilution effect.
- Supported catalyst is effective for the addition of dialkylzinc reagents to aldehydes.
- The supported system can be used for 5 cycles without lost of its efficiency.
