Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...
