Polymergebundene Nitrone

, 2002
In den letzten Jahren ist die Nachfrage nach Datenspeichern und ihrer Speicherkapazität immer größer geworden. Dazu sind neue Speichermaterialien notwendig sind, wofür sich in vielen Fällen polymere schaltbare Materialien eignen.Aus diesem Grunde wurden in der vorliegenden Arbeit polymergebundene Nitrone hergestellt, um diese als photoreaktives ...

Rate Constants of Hydroperoxyl Radical Addition to Cyclic Nitrones:  A DFT Study

, 2016
Nitrones are potential synthetic antioxidants against the reduction of radical-mediated oxidative damage in cells and as analytical reagents for the identification of HO2• and other such transient species. In this work, the PCM/B3LYP/6-31+G(d,p)//B3LYP/6-

Study of 1,3-Dipolar Cycloaddition Between 4-Acyl-1H-pyrrole-2,3-diones Fused at the [e]-Side with a Heterocyclic Moiety and Diphenylnitrone: A Comprehensive MEDT, Docking Approach and MD Simulation

Molecules
In this article, the 1,3-dipolar cycloaddition (1,3-DC) reactions between 4-acyl-1H-pyrrole-2,3-diones fused at the [e]-side with a heterocyclic moiety (FPDs) and diphenylnitrone are studied using Molecular Electron Density Theory (MEDT) at different ...

Copper-Catalyzed Disruption of a Cascade Reaction: Synthesis of γ-Ketoamides from Nitrones and Ynamides

A thermal dipolar cycloaddition and rearrangement reaction to form pyrrolines has been redirected towards the synthesis of γ-keto- and γ-aldoamides from nitrones and ynamides with a Cu(II) catalyst.

Targeting mitochondria with novel, differently vectorized linear phosphorylated nitrones:

, 2020
The free radicals (FR) occurrence in biological signalling or as pathologies triggers is well-documented and the design of specific scavengers to limit oxidative stress is enthralling. Because FR become inactivated upon addition to nitrones, efforts have

Reactivity of tetrapyrrolyl nitrones towards dipolarophiles bearing electron-withdrawing groups

The reactivity of porphyrinyl and corrolyl nitrones towards dipolarophiles bearing electron-withdrawing groups was studied and it was found that the two nitrones behave differently in 1,3-dipolar cycloaddition reactions.
