二亚硝基钴配合物可用于烯烃与不饱和烯酮和酮亚胺的[3+2]成环反应。在 Sc(OTf)3/LHMDS 存在下,一系列二亚硝基钴/烯烃加合物与共轭受体发生反应,在底物亚硝酰基的 α 碳位置形成两个新的 C-C 键,从而产生不寻常的三环和四环。这些产物在降冰片二烯存在下进行逆环加成得到官能化的四取代双环烯烃。
The utility of cobalt dinitrosyl complexes for the [3+2] annulation of alkenes with unsaturated enones and ketimines has been demonstrated. Reaction of a series of cobalt dinitrosyl/alkene adducts with conjugate acceptors in the presence of Sc(OTf)3/LHMDS formed two new C-C bonds at the carbons α to the nitrosyl groups of the substrate, leading to unusual tri- and tetracycles. Retrocycloaddition of these products in the presence of norbornadiene yielded functionalized tetrasubstituted bicyclic olefins.
