Synthesis of polysubstituted 1,2-dihydroisoquinolines via a CuI-catalyzed arylation/condensation cascade process
摘要:
CuI-catalyzed reaction of 1-(2-bromophenyl)-propargylamines 4 with beta-keto esters in i-PrOH/H2O (3:1) at 50 degrees C provides polysubstituted 1,2-dihydroisoquinolines. The transformation involves a cascade intermolecular C-C bond formation and intramolecular condensation process. (C) 2009 Elsevier Ltd. All rights reserved.
