Ein portalpräorganisiertes Cucurbit[7]uril‐Ruthenium‐Konjugat ermöglicht motivselektive Proteindetektion

Angewandte Chemie, EarlyView.
Die gezielte Veränderung der Erkennungsumgebung am Portal von Cucurbit[7]uril (CB7) wandelt einen Wirt ohne intrinsisches optisches Signal in einen motivselektiven photolumineszenten Rezeptor um. Das am Portal vororganisierte CB7‐Rubpy‐Konjugat zeigt Änderungen der Zugänglichkeit aromatischer Motive unmittelbar an und ermöglicht dadurch die optische ...

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.

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 ...
