Direct C─H Lactonization of Carboxylic Acids Enabled by LMCT Photoactivation
Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.We report a photochemical method for oxidative γ‐C─H lactonization of simple carboxylic acid substrates upon LMCT photoactivation. Intriguingly, these conditions suppress the rapid decarboxylation characteristic of oxidized carboxylates, suggesting the intermediacy of metal‐stabilized acyloxy radical instead of the dissociative process typically ...

Angewandte Chemie International Edition, EarlyView.Chiral cyclopropenimine–thiourea organocatalysts enabled both high reactivity and precise stereocontrol in the ring‐opening polymerization of rac‐lactide. The bifunctional system exhibited a TOF up to 1,710 h−1 with Pm = 0.90 at 25°C, and achieved Pm = 0.99 at −78°C while maintaining a TOF of 16.3 h−1.
