Co2+ bis((S,S)- or (R,R)-N,N′-dibenzylcyclohexane-1,2-diamine) complexes resulted in the formation of Michael adducts with two stereo-centers which were used as key precursors for the preparation of potentially biologically active enantiopure 4,5-disubstituted pyrrolidin-2-one derivatives.
在手性Mg 2+双恶唑啉配合物和Ni 2+和Co 2+ bis((S,S)-或(R,R)-N,N的存在下,将丙二酸酯添加到反式-β-烷基-β-硝基苯乙烯中′-二苄基环己烷-1,2-二胺)配合物形成带有两个立体中心的迈克尔加成物,它们被用作制备潜在的具有生物活性的对映体纯的4,5-二取代的吡咯烷-2-一衍生物的关键前体。
