我们成功地证明了铁或钴催化的二乙烯基酮的不对称Nazarov环化反应，使用铁或钴催化剂，其由Co（ClO（4））（2）中心点6H（2）O，Fe（ClO（4））（2）中心点6H（2）O或Fe（OTf）（2）与手性pybox型配体制备。此外，我们还发现Fe（OTf）（2）有效地催化了二乙烯基酮的串联Nazarov环化反应.
We succeeded in demonstrating the iron- or cobalt-catalyzed asymmetric Nazarov cyclization of divinyl ketones using iron or cobalt catalysts, which were prepared from Co(ClO(4))(2)center dot 6H(2)O, Fe(ClO(4))(2)center dot 6H(2)O, or Fe(OTf)(2) with a chiral pybox-type ligand. Furthermore, we found that Fe(OTf)(2) effectively catalyzed the tandem Nazarov cyclization-fluorination reaction of divinyl ketones.
