Advanced Science, EarlyView.Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

(1H-Benzo[d][1,2,3]triazol-1-yl)(5-bromo-1-hydroxy-1H-indol-3-yl)methanone
Molbank, 2014 The title compound was easily prepared by a nitrosoarene-alkyne cycloaddition reaction carried out in toluene at 80 °C. The product is a highly functionalized compound that can be further derivatized through various functional group interconversion ...

The Neber Route to Substituted Indoles
, 2016 Two complementary procedures have been developed for the conversion of the oximes of α-aryl ketones to azirines. On heating, the azirines rearrange smoothly to the corresponding indoles.

Advanced Science, EarlyView.Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

Advanced Science, EarlyView.A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Radical intermediates in the peroxidation of indoles
, 2001 2-Substituted and 1,2-disubstituted indoles react with m-chloroperbenzoic acid and hydrogen peroxide in the presence of acid or calcium chloride affording 2- and 3-(3-oxoindol-2-yl)indoles; whereas 2,3-disubstituted indoles, reacting with the same ...

Photocatalytic Alkylation of Pyrroles and Indoles with α-Diazo Esters [PDF]
, 2019 This article describes direct photoalkylation of electron-rich aromatic compounds with diazo compoiunds. C-2 alkylated indoles and pyrroles are obtained with good yields even though the photocatalyst (Ru(bpy)3Cl2) loading is as low as 0.075 mol %.
