Catalyst design within asymmetric organocatalysis
WIREs Computational Molecular Science, 2022 AbstractThe field of organocatalysis, more specifically asymmetric organocatalysis, is continuously expanding having grown significantly over the recent years. However, despite this exponential expansion, the ability to determine with any degree of certainty the reaction mechanisms of these types of reactions fails to keep within pace.

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance
Chemistry – A European Journal, EarlyView.This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Enantiopurity‐Dependent Peptide Coacervates and Asymmetric Organocatalysis
Small, EarlyView.Enantiopure peptide LLLPFF‐OCH3 forms liquid–liquid phase‐separated (LLPS) droplets that act as chiral microreactors for enantioselective aldol catalysis. Racemic mixtures fail to undergo LLPS, showing spontaneous enantiomeric self‐disproportionation (SDE).
