New Concepts for Organocatalysis [PDF]
, 2008 Organocatalysis, catalysis with low-molecular weight catalysts in which a metal is not part of the catalytic principle or the reaction substrate, can be as efficient and selective as metal- or biocatalysis.

Cupreines and cupreidines: an established class of bifunctional cinchona organocatalysts
Beilstein Journal of Organic Chemistry, 2016 Cinchona alkaloids with a free 6'-OH functionality are being increasingly used within asymmetric organocatalysis. This fascinating class of bifunctional catalyst offers a genuine alternative to the more commonly used thiourea systems and because of the ...

Multistep Chemoenzymatic Cascade for the Synthesis of Chiral N‐Heterocycles
ChemCatChem, Volume 18, Issue 13, 14 July 2026.We describe a multistep cascade to access quinolizidine and indolizidine containing compounds that incorporates a transaminase to generate a reactive intermediate in situ and subsequent proline‐mediated Mannich‐aza‐Michael reaction for the construction of privileged aza‐bicyclic scaffolds.

Non-covalent organocatalysis in asymmetric oxidative C(sp3)–H bond functionalization – broadening C–H bond coupling reactions [PDF]
, 2016 Among the current huge development activities in C-H functionalization, asymmetric oxidative C(sp(3))-H bond coupling strategies have remained underrepresented. Beyond the initial examples using chiral metal complexes, the use of organocatalysis provides

Asymmetric Counteranion-Directed Lewis Acid Organocatalysis. [PDF]
, 2014 This work describes studies on asymmetric counteranion-directed Lewis acid organocatalysis. In the first part, the development of a catalytic asymmetric Hosomi–Sakurai reaction using BINOL-derived disulfonimides is described. Good to excellent yields and

Searching for untrodden paths in organocatalysis territory [PDF]
, 2010 In spite of the tremendous growth experienced by the field of asymmetric organocatalysis in the last decade, it is important to realize that we are still far away from having explored all of the possible pathways in organocatalysis ‘territory'; the ...
