Regioselective lithium–halogen exchange and palladium-catalyzed cross-coupling reactions of 2,4-dihaloquinolines
摘要:
Lithium-halogen exchange of 2,4-dibromoquinolines proceeds regioselectively at C-4 and affords 4-substituted quinolines on quenching with electrophiles. Palladium-catalyzed cross-coupling reactions of 2-bromo-4-iodoquinoline provide 4-substituted 2-bromoquinoline derivatives. (c) 2005 Elsevier Ltd. All rights reserved.
