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。
