Enamine catalysis enables the first catalytic enantioselective Friedländer reaction. The desymmetrization of 4-substituted cyclohexanones upon reaction with o-aminobenzaldehydes allows for the synthesis of quinolines with remote stereogenic centers. These heterocycles, which are obtained with high levels of enantioselectivity, serve as precursors for chiral tacrine analogues.
烯胺催化可实现第一个催化对映选择性弗里德兰德反应。与邻氨基苯甲醛反应后,4-取代的环己酮的脱对称化使得可以合成具有远程立体中心的喹啉。这些具有高水平对映选择性的杂环用作手性他克林类似物的前体。
