Abstract
本論文是在探討以 3 mol %一價銠金屬及本實驗室所開發的雙環[2.2.1]樟腦型醯胺類雙烯配基 L7j 或雙環[2.2.1]樟腦型雙烯配基 L6i所形成的錯合物,以 1,4-二噁烷作為溶劑並在 100°C 下進行,催化一系列芳香基硼鹽對喹啉進行不對稱 1,2-加成反應,得到一系列以 氮-苄基-2-苯基-1,2-二氫喹啉化合物, 有高達 90%的產率以及 92%的鏡像超越值。
In this thesis, enantioselective arylation of N-Benzyl quinolinium salts is described. In the presence of 3 mol % ofthe catalyst generated in situ from [RhCl(C2H4)2]2 and chiral bicycloheptadiene ligand L7j or L6i, reaction of various quinolinium tetraarylborates gives rise to the corresponding enantio-enriched N-benzoy-2-aryl-1,2-dihydroquinolines in up to 90% yield with up to 92% ee at 100°C in dioxane.
