摘要
A series of experiments was performed to determine the nature of the catalyst in peptide-derived phosphine ligands. The selectivity of the catalyst system was determined with four ligands that are diastereomeric at the phosphine containing amino acid. Additionally, a series of monophosphine ligands was synthesized and screened to determine if the active catalysts are derived from a phosphine-amide complex. (C) 2004 Elsevier Ltd.
