應用
不对称催化作用的 C2 对称配体。由于噁唑啉氮具有对各种金属的强亲合性,因此容易形成双齿配位络合物。
(+)-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.

A highly enantioselective (up to 97.5% ee) and diastereoselective (95:5 dr trans/cis) Cu(I)-catalyzed cyclopropanation of alkenes using phenyliodonium ylide generated in situ from iodosobenzene and methyl nitroacetate is reported. The cyclopropanation took place with high enantioselectivity for a wide range
