The Diarylprolinol Silyl Ethers: After 20 Years Still Opening New Doors in Asymmetric Catalysis

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Catalysis Rules! The year 2025 marks the 20th anniversary of diarylprolinol silyl ethers in asymmetric organocatalysis. During the first decade after their discovery, these catalysts have been established as one of the most versatile tools in aminocatalysis. Although now considered mature, recent years have witnessed renewed innovation.

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).

Ortho-Carborane-Derived Halogen Bonding Organocatalysts

Angewandte Chemie International Edition
Multidentate neutral halogen bonding (XB) catalysts based on iodinated icosahedral ortho-carborane moieties are introduced. Co-crystallization-studies, calorimetric measurements, and 1H NMR titrations demonstrate their strong binding to halides and neutral compounds, further underlined by quantum-chemical calculations.
