✦ Synopsis

A highly enantioselective allylation of oximes of ct-ketoesters is described with phenyl substituted chiral bis(oxazoline) as external ligand of allylzinc reagents. This method provides an efficient and convenient access to N-benzyloxy allylglycine, allylglycine and chain substituted variants with high enantiomeric purities.
