A Ruthenium(CAAC-5) Olefin Metathesis Catalyst for Bioconjugation. [PDF]
Angew Chem Int Ed EnglThe 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 ...
