Synthesis and Characterization of New, Chiral P−N Ligands and Their Use in Asymmetric Allylic Alkylation
Abstract
Several new ferrocenylimines containing both planar and central chirality were prepared from (Sp)-2-(diphenylphosphino)ferrocenecarboxaldehyde and chiral primary amines. One of these compounds, (Sp,Sc)-3, induced particularly high conversions (92−99%) and enantioselectivities (91−94% ee) when applied as a P−N ligand in the asymmetric allylic alkylation (AAA). In addition, a precatalyst complex was formed from (Sp,Sc)-3 and...
