Asymmetric Synthesis of Atropisomeric Amines via Transaminase‐Catalyzed Dynamic Kinetic Resolution

open access: yesAdvanced 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.

Sequential Carboborylation–Suzuki Coupling of α,β‐Unsaturated Tosylhydrazones: A Dual CC Bond‐Forming Strategy for Molecular Diversification

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
Structural diversity can be generated from α,β‐unsaturated carbonyls via N‐tosylhydrazones through a one‐pot‐three‐component photochemically promoted carboborylation/allylic Suzuki sequence. The wide availability and scope regarding each of three reaction partners: carbonyls, alkylboronic acids, and aryl halides, and the functionalities available in ...

Copper‐Catalyzed Defluorinative Allylboration of Allenes with Trifluoromethyl Alkenes

open access: yesChemistryEurope, 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
