The extraordinary rate accelerations and control of reactivity exhibited by enzymes have long inspired efforts to develop synthetic catalysts. Foldamers, which are oligomers with a strong tendency to adopt a specific conformation, represent unique platforms for efforts to harness principles of enzyme function for catalyst design.

The reversible reaction of primary or secondary amines with enolizable aldehydes or ketones affords nucleophilic intermediates, enamines. With chiral amines, catalytic enantioselective reactions via enamine intermediates become possible. In this review, structure-activity relationships and the scope as well as current limitations of enamine catalysis ...

Catalysts often perform miraculous transformations of reactants A to very different products P in seemingly a single step. Such catalysts appear as a black box. This tutorial shows how we can shine light into this black box and understand the reaction mechanism.

Heterogeneous catalysts are plentiful in the chemical industry. In this chapter, a short overview will be given on the steps needed to convert a reactant into a product over a heterogeneous catalyst. In addition, an introduction will be given on the way a catalyst assists in the making and breaking of chemical bonds.
