Abstract
The asymmetric hydroalkylation of racemic allylic alcohols has been developed for the synthesis of chiral amino acid derivatives with two remote chiral centers by borrowing hydrogen catalysis. The stereoselectivities are controlled by a single chiral Ru catalyst via a dynamic kinetic asymmetric transformation process and an interesting diastereoselectivity amplification process of the product. The method could be used for the synthesis of several types of biologically important molecules, including stereodivergent synthesis of chiral pyrrolidine derivatives.
