Pyrene‐Conjugated, 2‐Pyridinecarboxaldehyde Derivatives as N‐Terminus‐Specific Tags for MALDI‐ and LALDI‐MS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Background Proteolytic processing is a fundamental post‐translational modification. Liquid chromatography–tandem mass spectrometry (LC–MS/MS) workflows are powerful for degradomic analyses but inherently sacrifice spatial information, a critical aspect for investigating biological systems such as aberrant extracellular matrix remodeling and ...

A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.
