Stereochemical Control in the Matteson Reaction
Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Selective N‐Functionalization of Pyrazoles
European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Sustainable Diepoxide Monomers for Polyoxazolidinone‐Based High‐Performance Thermoplastics
ChemSusChem, Volume 19, Issue 19, 14 October 2026.Sustainable diglycidyl ethers could replace bisphenol A diglycidyl ether (BADGE) as a building block for polyoxazolidinones, yielding high‐performance thermoplastics with similar thermal and mechanical properties. Owing to their outstanding mechanical, thermal, and chemical properties, polyoxazolidinones, which are accessible from the reaction of ...

Enzymatic Allylation of Catechols
, 2015 Enzymatic allylation of catechols was realized via catechol O-methyltransferase (COMT) using an allylated S-adenosyl-L-methionine (allyl-SAM) analog, with relatively good chemo- and regioselectivities.
