Expanding the Scope of 1,2‐Diazepines Through Alternative Activation Strategies

European Journal of Organic Chemistry, Volume 29, Issue 35, 19 September 2026.
Often overlooked due to tedious synthetic routes, 1,2‐diazepines can be found in handful of biorelevant molecules. Previous reports from our group lifted the principal synthetic lock: a rapid and user‐friendly protocol to reach monocyclic 1,2‐diazepines from readily available pyridines and electrophilic activating groups. Herein, we extend the scope of

A Solvent‐Free Approach for the Mechanochemical Upcycling of Bio‐ and Fossil‐Based Polyesters Into Value‐Added Chemicals and Bio‐Based Plasticizers

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
Mechanochemical upcycling of bio‐ and fossil‐based polyesters with alcohols and amines using MeONa as the catalyst selectively produces synthetically useful diesters and diamides, giving only alcohols as byproducts. This green and efficient protocol is readily scalable and can be transferred to the upcycling of polyester‐based postconsumer waste ...
