Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

Angewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

A Ruthenium(CAAC‐5) Olefin Metathesis Catalyst for Bioconjugation

Angewandte Chemie International Edition, EarlyView.
The aqueous instability of ruthenium catalysts restricts olefin metathesis in biological media. A Ru(CAAC‐5) complex bearing an aniline handle is reported that remains active under biologically relevant conditions and enables bioconjugation to proteins, peptides, and an artificial metalloenzyme, providing a robust platform for olefin metathesis in ...
