A copper-catalyzed arylation of tryptamines for the direct synthesis of aryl pyrroloindolines [PDF]
, 2012 An operationally simple, copper-catalyzed arylation of N-tosyltryptamines provides direct access to C3-aryl pyrroloindolines. A range of electron-donating and electron-withdrawing substituents is tolerated on both the indole backbone and the aryl ...

Effective Low‐Temperature Oxidative Denitrogenation With Sulfated Titania Supported on Porous Carbon
Small Structures, Volume 7, Issue 1, January 2026.We report the first synthesis of the novel S‐TiO2/C catalyst on highly porous pANI‐derived carbon. It achieved outstanding oxidative denitrogenation (ODN) performance, completing conversion of 1000 ppm indole in 60 min at 45°C. This is due to well‐dispersed S‐TiO2 facilitating H2O2 activation and •OH radical generation, and it proved highly reusable ...

Journal of Immunology Research, Volume 2026, Issue 1, 2026.In clinical practice, Hezi Qingyou Formula (HZQYF) has been observed to effectively alleviate clinical symptoms associated with gastri ulcers, though its precise mechanism of action remains unclear. To investigate the effects of HZQYF on gastric ulcers, we established a rat model of gastric ulcer and examined its impact on ulcer area, pathological ...
