Novel 5’‐Substituted Cinchona‐Derived Organocatalysts: Synthesis, Reactivity, and Dual Activation Potential Open
This work presents the synthesis of three little‐investigated types of asymmetric cinchona organocatalysts. The cinchona moiety is considered one of the privileged chiral skeletons, and one of its well‐known modifications involves attachin…

Factors influencing the performance of organocatalysts immobilised on solid supports: A review Open
Organocatalysis has become a powerful tool in synthetic chemistry, providing a cost-effective alternative to traditional catalytic methods. The immobilisation of organocatalysts offers the potential to increase catalyst reusability and eff…

Cinchona‐Based Hydrogen‐Bond Donor Organocatalyst Metal Complexes: Asymmetric Catalysis and Structure Determination Open
In this study, we describe the synthesis of cinchona (thio)squaramide and a novel cinchona thiourea organocatalyst. These catalysts were employed in pharmaceutically relevant catalytic asymmetric reactions, such as Michael, Friedel–Crafts,…

Synthesis of Novel Crown Ether-Squaramides and Their Application as Phase-Transfer Catalysts Open
This work presents the synthesis of six new phase-transfer organocatalysts in which the squaramide unit is directly linked to the nitrogen atom of an aza-crown ether. Four chiral skeletons, namely hydroquinine, quinine, cinchonine (cinchon…
