Enantioselective fluorination of β-ketoesters catalysed by complexes of new mono-oxazoline ligands

Abstract A new kind of mono-oxazoline ligands which combined diaryl methyl units and chiral oxazoline units together using pyridine as linker was prepared. Their applications in enantioselective electrophilic fluorination of β -ketoesters by NFSI were investigated, and the corresponding products were obtained in excellent yield (up to 90%) and good enantioselectivity (78%) in CH 2 Cl 2 at −60 °C.
