Copper-catalyzed enantioselective conjugate addition of dialkylzinc reagents to enones with new peptidyl phosphane ligands
摘要:
Copper catalysts based on new peptidyl phosphane ligands have been developed for enantioselective conjugate additions of dialkylzinc reagents to cyclic enones. Enantioselectivities greater than 97% ee have been observed. (C) 2003 Elsevier Ltd. All rights reserved.
