英文摘要	a series of bis(oxazolinyl)pyridine (pybox) ligands, with different electronic and steric properties were synthesized and evaluated in the sc(iii)catalyzed asymmetric diels-alder reaction of alkenoyl-1,3-oxazolidin-2-ones with cyclopentadiene. the results show that electron-withdrawing groups increase the enantioselectivity, which is more significantly influenced by steric effects arising near the metal center. up to 96% ee was obtained under mild reaction conditions when using a ligand containing the sterically bulky tbu substituent and electron-withdrawing chloride.
