Synthesis and bioactivities of novel 4,5,6,7-Tetrahydrothieno[2,3-c]pyridines as inhibitors of tumor necrosis factor-α (TNF-α) production
摘要:
Novel 4,5,6,7-tetraliydrothieno[2,3-c]pyridine derivatives were synthesized and evaluated for their abilities to inhibit lipopolysaccharide (LPS)-stimulated production of TNF-alpha in rat whole blood. Several of these compounds exhibited potent inhibitory activity. (C) 2002 Elsevier Science Ltd. All rights reserved.

palladium(II)-catalyzed decarboxylative protocol for the synthesis of aryl ketones has been developed. The addition of TFA was shown to improve the reaction yield and employing THF as solvent enabled the use of solid nitriles and in only a small excess. Using this method, five different benzoic acids reacted with a wide range of nitriles to produce 29 diverse (hetero)aryl ketone derivatives in up to 94% yield.
