An enantioselective synthesis of β2-amino acid derivatives
摘要:
Enantioselective hydrogenation of a series of (E)-alpha-substituted beta-amidoacrylates using Rh(I)-catalysts with chiral phosphine ligands (BPE, DuPHOS) gives beta(2)-amino acid derivatives with enantioselectivities of up to 67%. A beta(2,3)-amino acid derivative was also synthesised with similar enantioselectivity (<= 65%) from the corresponding prochiral enamide. (c) 2005 Elsevier Ltd. All rights reserved.
