Application

C2 symmetric ligand for enantioselective catalysis. Easily forms bidentate coordination complexes due to the strong affinity of the oxazoline nitrogen for various metals.
(+)-2,2′-Isopropylidenebis[(4R)-4-phenyl-2-oxazoline] in the presence of copper iodide, can catalyze the asymmetric cyclopropanation reaction of phenyliodonium ylides with alkenes to form cyclopropane α-amino acid esters.
