Stereocontrol in Conformationally Stable C(sp2)─C(sp3) Atropisomers

Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.
Building in our expertize in the synthesis of trans‐dihydrobenzofurans via organocatalyzed domino Michael/O‐cyclization between β‐naphthols and nitroalkenes, we developed an efficient strategy to access a new family of atropisomers bearing a conformationally stable C(sp2)─C(sp3) bond and two stereogenic centers through simple and highly ...

Proteomic analysis of peptides tagged with dimedone and related probes [PDF]

Journal of Mass Spectrometry, 2014
Owing to its labile nature, a new role for cysteine sulfenic acid (–SOH) modification has emerged. This oxidative modification modulates protein function by acting as a redox switch during cellular signaling. The identification of proteins that undergo this modification represents a methodological challenge, and its resolution remains a matter of ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

Advanced Materials, Volume 37, Issue 52, December 29, 2025.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

H2S Is a Potential Universal Reducing Agent for Prx6‐Type Peroxiredoxins

Advanced Science, Volume 12, Issue 46, December 11, 2025.
We report the identification of H2S as reducing agent for Prx6‐type peroxiredoxins. In contrast to common physiological reducing agents of other peroxiredoxins, HS− is small enough to access the active site of oxidized Prx6‐type enzymes in the fully‐folded protein conformation.

N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis

Advanced Synthesis &Catalysis, Volume 367, Issue 22, November 28, 2025.
Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Advances in Enaminomaleimides Chemistry: Synthesis, Chemical Applications, and Perspectives

ChemistryEurope, Volume 3, Issue 5, September 18, 2025.
Enaminomaleimides are versatile building blocks for the construction of functionalized heterocycles. Their unique nucleophilic character, contrasting with the classical electrophilic nature of maleimides, enables diverse synthetic applications, showing promising potential in both materials science and medicinal chemistry.
