Abstract

Heterogeneous catalytic asymmetric hydrogenation reactions have a complex character. The complexity arises from the fact that for the catalytic step the metal surface is required, while for the asymmetric induction a chiral template molecule is needed, that carries the chiral information to the prochiral substrate molecule. In heterogeneous catalytic asymmetric hydrogenation reactions the main question to be answered is: how and where the transfer of the chiral information takes place. There are two possibilities to transfer the chiral information: i) transfer at the metal surface, and ii) transfer in the bulk liquid phase. In order to answer the above questions previous and recent results have been analyzed. Examples are taken from two case studies: enantioselective hydrogenation of α-keto esters and β-keto esters and related compounds. The comparison shows that the two systems are completely different. In the first part general information about the two catalytic systems is provided, while in the second part new methods and approaches applied into this field will be discussed.
