Chelating 2-azanorbornyl derivatives as effective nitrogen–nitrogen and nitrogen–chalcogen donating ligands in palladium-catalyzed asymmetric allylic alkylation
摘要:
New chiral 2-azanorbornane derivatives were prepared and used as (N,S)-, (N,Se)-, and (N,N)-donating ligands in a palladium-catalyzed asymmetric allylic alkylation, giving up to 95% ee and 92% yield. (C) 2008 Elsevier Ltd. All rights reserved.
