The manuscript describes an utilization of 5-substituted-furan-2(3H)-ones as pronucleophiles in an asymmetric vinylogous Michael addition to an α,β-unsaturated-γ-lactam, thus leading to hybrid molecules possessing γ-lactam and butenolide structural motifs. The transformation utilizes two potentially vinylogous pronucleophiles and has been realized by simultaneous activation of both substrates by a
该手稿描述了将 5-取代的呋喃-2(3 H )-ones 作为亲核试剂在不对称插藤迈克尔加成到 α、β-不饱和-γ-内酰胺中的应用,从而产生具有 γ-内酰胺和丁烯内酯的杂化分子结构图案。该转化利用了两种潜在的乙烯基原亲核试剂,并通过衍生自金鸡纳生物碱的双功能有机催化剂同时激活两种底物来实现。反应以高度对映选择性和非对映选择性方式发生,目标产物的合成潜力已在立体选择性转化中得到证实。
