Synthesis of Atropisomeric Two-Axis Systems by the Catalyst-Controlled syn- and anti-Selective Arene-Forming Aldol Condensation

Very well done Daniel and many congratulations. This stereodivergent approach allows the programmed one-step synthesis of all four feasible atropisomeric two-axis systems.

Stereoselective Synthesis of Atropisomeric Acridinium Salts by the Catalyst-Controlled Cyclization of ortho-Quinone Methide Iminiums

Many congratulations to Xingxing for establishing a stereoselective route to atropisomeric acridinium salts by a Friedel-Crafts electrocyclization of ortho-quinone methide iminiums by means of ion-pairing catalysis.

Catalyst-Controlled Stereoselective Barton–Kellogg Olefination

Many Congratulations. Tanno achieved an important milestone for our research: the catalyst-controlled thiiranation combined with stereospecific reductions to overcrowded alkenes, also in a fully stereodivergent manner.
ERC

ERC Consolidator Grant

We recently started our project "Catalyst Control over X-Fold Stereogenicity" supported by an ERC Consolidator Grant. Join our team: PhD and Postdoc positions are available.

Ad Hoc Adjustment of Photoredox Properties by the Late-Stage Diversification of Acridinium Photocatalysts

Well done Valeriia. Acridinium photocatalysts can now be late-stage diversified to adjust their redox properties (including the new aza-rhodol photoredox catalysts), now published in Org. Lett.

Catalyst Control over Twofold and Higher-Order Stereogenicity by Atroposelective Arene Formation

Congratulations Tanno. Our ongoing journey through the realms of atropisomeric molecules, now outlined in Acc. Chem. Res.

Monitoring Solid-phase Reactions in Self-assembled Monolayers by Surface-enhanced Raman Spectroscopy,

Well done Dominik, Mayor and Lörtscher IBM research teams. Monitoring Solid-phase Reactions in Self-assembled Monolayers by Surface-enhanced Raman Spectroscopy, now published in Angew. Chem. Int. Ed.

Catalyst control over sixfold stereogenicity

Wonderful achievement by Xingxing, Reto, Rodolphe, Christian and Daniel. Stereoselective catalysis allows to navigate stereochemical space beyond binary (Le Bel–Van ’t Hoff rule), now published in Nature Catalysis. Very proud of the team.
