N,N'-双(2-喹啉亚甲基)-1,1'-联萘-2,2'-二胺-Ni(II)络合物和类似络合物被发现是有效的手性路易斯酸催化剂，用于2-甲硅烷氧基呋喃和3-烯酰基-2-恶唑烷酮之间的不对称迈克尔加成反应，获得高达97% ee的不对称诱导。
N,N'-Bis(2-quinolylmethylene)-1,1'-binaphthyl-2,2'-diamine-Ni(II) complex and analogous complexes were found to be efficient chiral Lewis acid catalysts for the asymmetric Michael addition reactions between 2-silyloxyfurans and 3-alkenoyl-2-oxazolidinones, for which asymmetric inductions of up to 97% ee were obtained.
