Pd/Cu-catalyzed couplings of β-amino esters with aryl bromides. Synthesis of chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-1-quinolines
摘要:
A new protocol to prepare chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-1-quinolines has been developed. The key steps are Pd/Cu-catalyzed couplings of chiral beta-amino esters and aryl bromides, and intramolecular acylation. (C) 1998 Elsevier Science Ltd. All rights reserved.
