On the Origin of Substrate Specificity of Enzymes from the Amidohydrolase Superfamily

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
Comprehensive analyses of two enzyme classes from the amidohydrolase superfamily (AHS) revealed that catalysis proceeds either via 1,4 or 1,6 nucleophilic conjugate addition and that this property defines substrate specificity. Moreover, although all substrates and products are entirely achiral, this mechanistic difference results in an inverted ...

Enantioselective Syntheses of Secondary Alkylboronates via Asymmetric Regioselective Reduction of 1,3‐Dienylboronates

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
We report herein the development of catalytic asymmetric synthesis of secondary alkyl boronates. Under the optimal conditions, Cu‐catalyzed semi‐reduction of 1‐alkyl‐ or 1,3‐dialkyl‐substituted 1‐boryl‐1,3‐butadienes forms secondary alkyl boronates with excellent regioselectivities and enantioselectivities.

Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic

Solvation Entropy as a Lever for Steering the Macroscopic Properties of a Functional Supramolecular Helical Polymer

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...
