A visible-light-promoted metal-free decarboxylative coupling protocol for the acylation of electron-deficient quinolines using ambient air as an oxidant has been disclosed. This environmental-friendly protocol takes place under mild conditions and is highlighted by using inexpensive photocatalyst and starting materials, thereby integrating C–H functionalization and recent photoredox scenario based

The facile cross-coupling reactivity of triarylbismuth compounds with aryl iodides was achieved under mild heating conditions. The established catalytic protocol using Pd(OAc)(2)(Cy2NH)(2) system exhibited high coupling reactivity with a variety of triarylbismuth and aryl iodide compounds under mild conditions. These coupling reactions were completed in short reaction time affording good to high yields of functionalized biaryl products. The studies of multi-coupling reactions with tris(4-iodophenyl)amine, 8 also furnished moderate to good yields of coupled products, 8a-8f. (C) 2010 Elsevier Ltd. All rights reserved.

atherosclerosis. The activity of the initially synthesized antihyperlipidemic morpholine derivatives (1–6), in which we combined several pharmacophore moieties, was evaluated in vitro (antioxidant, inhibition of SQS and lipoxygenase) and in vivo (anti-dyslipidemic and anti-inflammatory effect). We further compared the in vitro SQS inhibitory action of these derivatives with theoretically derived molecular
