Organocatalysis is a relatively new field of organic synthesis. It originated from the idea of emulating enzymatic catalysis with small-weight organic molecules and has grown since into a mature discipline providing catalysts for many different functional group transformations . Reports of organocatalysis comprise classical acid or base catalyzed organic reactions such as Michael , Mannich , Friedel-Crafts and Strecker reactions , but they also include C-C coupling methods typically catalyzed by a transition metal such as the Suzuki , Sonogashira , Ullman and Tsuji-Trost coupling reactions.
