Synthesis of Anthraquinone Mono‐ and Diboron Complexes with Near‐Infrared Panchromatic Absorption

Chemistry – A European Journal, Volume 31, Issue 53, September 19, 2025.
Anthraquinone boron complexes bearing β‐iminoenolate ligand(s) exhibit strongly substituent‐dependent absorption properties. Unsubstituted monoboron and diboron complexes show sharp UV–Vis–NIR absorption spectra resulting from increased molecular rigidity induced by boron coordination.

Solid‐Phase Synthesis of 1,3,5,6‐Tetra‐Substituted 3,5‐Dihydroimidazo[4,5‐c][1,2]Thiazin‐4(1 H)‐One 2,2‐Dioxide Derivatives

Journal of Heterocyclic Chemistry, Volume 62, Issue 9, Page 938-943, September 2025.
Through an efficient solid‐phase synthesis method, 32 different 1,3,5,6‐tetra‐substituted 3,5‐dihydroimidazo[4,5‐c][1,2]thiazin‐4(1H)‐one 2,2‐dioxide derivatives were synthesized. The derivative library, with a total of four diversities, showed an overall yield of 7%–32% over 8 steps.
