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.

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.
