Presentation Prize for Valeriia Hutskalova
Many congratulations Valeriia for winning a best presentation prize at the Fall Meeting of the Swiss Chemical Society![TOC](/fileadmin/_processed_/2/5/csm_directconverge_news_370fa51d40.jpg?1648387376)
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.![ToC](/fileadmin/_processed_/c/2/csm_oQMIsNF_2be264013f.jpg?1644933976)
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.![Oeschinensee](/fileadmin/_processed_/9/8/csm_IMG_4595_093b33ab30.jpeg?1637333766)

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](/fileadmin/_processed_/c/8/csm_LOGO_ERC_b2d414d3a6.jpg?1619777217)
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.![TOC](/fileadmin/user_upload/sparr_chemie/P53TOCsmall.png?1623335802)
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.![TOC](/fileadmin/user_upload/sparr_chemie/P50TOC.jpeg?1619768042)
