Asymmetric Organocatalysis with Sulfones
Angewandte Chemie - International Edition, 2010AbstractAsymmetric organocatalysis has become a powerful tool for the synthesis of optically active compounds. Whereas early research mainly focused on combining simple reagents as a proof‐of‐concept for asymmetric organocatalysis, recent investigations are directed towards extending the concept to more target‐ and diversity‐oriented synthesis.

Asymmetric Organocatalysis Under Mechanochemical Conditions
Chemical Record, 2023AbstractAsymmetric organocatalysis is a robust methodology providing access to numerous valuable compounds while having green chemistry principles in mind. The realization of organocatalytic transformation under solvent‐free mechanochemical conditions brings additional benefits in terms of yields, selectivities, and, last but not least overall improved
