Asymmetric Synthesis of Atropisomeric Amines via Transaminase‐Catalyzed Dynamic Kinetic Resolution
Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.A dynamic kinetic resolution approach is developed for the atroposelective synthesis of heterobiaryl primary amines. Using transaminases and leveraging Lewis acid‐base interactions to induce racemization, a variety of axially chiral primary amines are produced in high yields and enantioselectivities.

Copper‐Catalyzed Defluorinative Allylboration of Allenes with Trifluoromethyl Alkenes
ChemistryEurope, Volume 4, Issue 1, January 2026.A copper‐catalyzed borylative coupling of allenes with 1‐trifluoromethyl alkenes is reported. The reaction selectively provides synthetically versatile borylated 1,1‐difluoro‐1,5‐dienes that can be converted into a range of medicinally relevant fluorinated compounds. Mechanistic studies reveal a key role of the catalytically generated LiCl by assisting
