Cuprate addition/electrophilic trapping
Electrophilic trapping of enolates generated when organocuprates are added to enones is a common strategy in organic synthesis, But Krische and coworkers argue that use of ketone, ester and nitrile electrophiles in such transformations are unprecedented (J Am Chem Soc 2004, 126, 4528), Reaction 1 shows a nice example in which the original addition reaction is made electrophilic using one of Feringa's monodentate phosphoramidate ligands.
Additions to unsaturated malonates
The specific Feringa ligand used in reaction 1 is not clearly stated in that paper, but it was probably or its enantiomer. The Feringa group …
