In the presence of 3.0 mol % of Rh(I)-catalyst, which is in situ generated from the [RhCl(C2H4)2]2 and the chiral bicyclo[2.2.1]heptadiene ligand L12i, the desired chiral indanes 60 are obtained in 13–>99% yields with 12–99% ees. This asymmetric transformation, which is triggered by the release of ring strain, not only forms two carbon-carbon bonds, but establishes three consecutive new chiral centers. Furthermore, in this thesis, we also discuss the reactivity difference between the strain olefins and the double bonds with leaving groups at allylic position.一價銠金屬催化不對稱合環反應掌性雙環[2.2.1]雙烯配基鏡像選擇性掌性茚烷芳基硼酯試劑降冰片烯衍生物Rhodium(I)-catalyzedasymmetric tandem annulationchiral bicyclo[2.2.1]diene ligandsenantioselectivechiral indanesarylboronic esternorbornene derivativesetd
