Interactions Between O‐Phospho‐L‐Serine and Trivalent Metal Ions: Studies in Solution and Solid State

European Journal of Inorganic Chemistry, EarlyView.
The interaction between the phosphorylated amino acid O‐phospho‐L‐serine and trivalent ions of f‐elements such as La3+, Eu3+, and Lu3+, supplemented by Y3+, has been studied in aqueous media. Nuclear magnetic resonance (NMR) spectroscopy in solution and in the solid state examined complex formation from the ligand perspective, while time‐resolved laser‐

Triptindane‐9,10,11‐triol: Threefold Hydride Transfer from Lithium Aluminum Hydride as the Key Step to C3‐Symmetrically Trifunctionalized Tribenzo[3.3.3]propellanes

European Journal of Organic Chemistry, EarlyView.
Threefold reduction of 9,10,11‐triptindanetrione with LiAlH4 or NaBH4 yields exclusively the C3‐symmetric triol, suggesting an intracomplex (“rolling”) mechanism. However, use of LiAlH4/LiAlD4 (1 : 1) reveals a preceding hydride exchange. Mechanistic implications are discussed including the reduction of the related diketone.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.
