Most of the early developments were based on transition metal/chiral ligand based asymmetric catalysis. The introduction of organic molecules capable of influencing basic organic reactions has ushered in the era of ‘organocatalysis’ in modern chemistry. The ability of organocatalysts to control asymmetric transformations in the key step is attributed mainly to supramolecular interactions, similar to enzymes in the biochemical reactions.Elimination of the use of potentially toxic metal ion based catalysis in the wake of this development goes well with the advent of green chemistry and realization of the commitment of the scientists towards environmental concerns.
