organokatalytische

Organokatalytische refers to processes that utilize small organic molecules as catalysts. These catalysts are distinct from traditional metal-based or enzyme-based catalysts, offering a unique set of advantages and applications in organic synthesis. Organocatalysis has emerged as a powerful third pillar of catalysis alongside metal catalysis and biocatalysis.

The development of organocatalysis has been driven by the need for more sustainable, selective, and cost-effective chemical transformations. Organocatalysts are often composed of readily available, non-toxic elements such as carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus. This makes them environmentally friendly and potentially cheaper to produce.

Key to the success of organocatalysis is the ability of these small organic molecules to activate substrates, facilitate bond formation, and control stereochemistry. They can operate through various mechanisms, including the formation of covalent intermediates, hydrogen bonding, or Lewis acid/base interactions. This versatility allows for a wide range of reactions to be catalyzed, such as asymmetric aldol reactions, Michael additions, Diels-Alder reactions, and epoxidations.

The field of organocatalysis has seen significant growth, with many new organocatalysts being discovered and applied to complex syntheses. The ability to achieve high enantioselectivity and diastereoselectivity under mild reaction conditions is a major advantage, making organocatalysis an increasingly important tool for chemists in academia and industry. It offers an alternative route for synthesizing chiral molecules, which are crucial for pharmaceuticals, agrochemicals, and advanced materials.
