New chiral ligands designed for palladium-catalysed asymmetric allylic alkylation
Abstract
New chiral phosphine ligands containing a chiral functional group remote from the phosphino-groups have been found to be effective in the palladium-catalysed reaction of allyl acetate with the enolate anion of 2-acetylcyclohexanone and give the allylated product in significant enantiomeric enrichment.
