Safe and Sustainable by Design (SSbD) Synthesis of Food and Personal Care Ingredients by Mechanochemistry

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
A Safe and Sustainable by Design (SSbD) mechanochemical approach was used to prepare a marketed sweetener from a biomass derivative used in flavoring industry. A personal care ingredient was also synthesized. The study also evaluated and compared the reactivity in of polymeric jars with that in of common conventional stainless steel or and zirconium ...

Strategic Functionalization of Benzylic C(sp3)H Bonds: Unlocking the Potential for Enantioselective δ‐Lactonization

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Recent advancements in bio‐inspired Mn‐catalyzed directed oxidations of carboxylic acids have provided promising pathways for the synthesis of a wide variety of chiral γ‐lactones. In our current study, however, we have established a catalytic route using 0.25 mol% of electron‐rich Mn‐catalyst Mn(dMMbpbp) that redirects the lactonization reaction to the

Highly Lewis Acidic In Situ‐Generated Boronic Acid Ester: A Practical Catalyst for Hosomi–Sakurai Conjugate Addition, Carbonyl‐Ene Reaction, and Silane‐Mediated Amide Reduction

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
An exceptionally Lewis acidic boronic acid ester, generated in situ from pentafluorophenylboronic acid and tetrabromonaphthalenediol, catalyzes three important chemical transformations at 1–10 mol% loading: the Hosomi–Sakurai allylation of α,β‐unsaturated ketones, intermolecular carbonyl‐ene reactions, and the reductions of tertiary amides to amines ...

Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.

Intermolecular Nuclear Spin Hyperpolarization Transfer via Cross‐Relaxation Triggers RASER of Solute Molecules

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Radiofrequency amplification by stimulated emission of radiation (RASER) of solutes was achieved via parahydrogen‐induced polarization (PHIP) and polarization transfer from the produced hyperpolarization donors to solutes via the intermolecular nuclear Overhauser effect (NOE).
