Organocatalytic Formal (3+2+1)‐Cycloaddition of Allenoates, Michael Acceptors, and Carbaldehydes
Chemistry – A European Journal, Volume 32, Issue 35, 19 September 2026.The use of secondary amine Lewis base organocatalysts allows for the unprecedented activation of allenoates for formal (3+2+1)‐cycloadditions with Michael acceptors and aromatic carbaldehydes. ABSTRACT Employing secondary amines as covalently interacting Lewis basic organocatalysts allows for the activation of electron‐deficient allenes (allenoates ...

Borylcyclopropanes: Synthetic Strategies and Applications
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Angewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.An on‐resin dual‐modification strategy for peptides is presented, comprising S‐alkynylation of peptide thiosulfonates and regioselective iridium‐catalyzed azide–thioalkyne cycloaddition. This method reliably provides access to peptides with intricate non‐canonical modifications, being compatible with complex peptides, alkynes and azides.

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

ChemMedChem, Volume 21, Issue 17, 14 September 2026.Antibiotics improved human life, but bacterial resistance makes surfaces and packaging disinfection critical. Quaternary ammonium salts (QAS) represent a possible alternative. In this work, new bis‐cationic QAS from 2,4,6‐trichloro‐1,3,5‐triazine (bis‐TQAS) were synthesized, showing excellent inhibition against Klebsiella pneumoniae, Escherichia coli ...

ChemMedChem, Volume 21, Issue 17, 14 September 2026.Protoporphyrin IX derivatives bearing piperazine or morpholine substituents exhibit enhanced cellular retention and photodynamic activity in triple‐negative breast cancer cells. Structural modification promotes oxidative stress, alters mitochondrial membrane potential, and increases caspase‐3 activity, providing new structure–activity relationship ...

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 ...
