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

open access: yesAngewandte 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.

TRPA1 channels: Novel targets of 1,4-dihydropyridines [PDF]

open access: yesChannels, 2008
Transient receptor potential type A1 (TRPA1) channels are cation permeable channels activated by irritant chemicals and pungent natural compounds. Their location in peptidergic sensory terminals innervating the skin and blood vessels makes them important effectors of vasodilator responses of neural origin.
