摘要:
Great success has been achieved in the enantioselective-catalyzed reactions over the past few years. In the various catalyst, C2-symmetric chiral bis(oxazoline)ligand-metal complexes accepted great attention in recent years for they showed effective enantioselection in various catalytic reactions and were easy to be prepared from available optically active amine acid[1]. For the test of enantioselective-catalyzed cyclopropanation from sulfonyl-carbanions and alkenes, a series of new bis(oxazolinyl)pyridine complexes were synthesized. Nickel and iron was found as effective catalysts in the cyclopropanation from sulfonylcarbanions in previous research[2]. Some nickel or iron bis(oxazolinyl)pyridines were prepared(scheme 1). These complexes were characterized with MS, IR and so on.
