Allylation using diimine ligand

More recently, Benaglia and coworkers reported that the allylation reaction of a-iminoesters proceeded to give the homoallyl alcohols with moderate enantioselectivities (Scheme 9.4).9 The chiral diimine that has a chiral 1,2-cyclohexyldiamine framework was used as the ligand. The reaction of a-iminoesters and allyltributyltin in the presence of AgOTf and diimine ligand proceeded to afford chiral amino acid derivatives with moderate enantioselectivities.
