dc.description.abstract本篇論文探討利用一價銠金屬試劑與掌性雙環[2.2.1]雙烯配基L1i配位形成之催化劑,於反應溫度60 ℃且使用1,4-二噁烷及水,比例為10:1為溶劑,並加入2當量碳酸鈉為添加劑的條件下,催化不同芳基硼酯1與不同炔烴化合物2進行不對稱環化反應,成功合成一系列具有含全碳四級立體中心的掌性茚化合物3,共有24個例子,產率65−96%,鏡像超越值高達98%。此外,以芳基硼酯1h及苯基丙炔2f進行反應,生成掌性茚化合物3hf,區域選擇性比例為9.4:1。zh_TW
dc.description.abstractThis thesis describes an enantioselective annulation of arylboronate esters 1 with internal alkynes 2 in 1,4-dioxane and water at 60 ℃ with 2 equiv of sodium carbonate as an additive in the presence of 3.0 mol % of Rh(I)-catalyst in situ generated from the [RhCl(C2H4)2]2 and chiral bicyclo[2.2.1]heptadiene ligand L1i, affording a series of chiral indene products 3 bearing an all-carbon quaternary stereogenic center in 65−96% yields with up to 98% ee.In addition, the reaction with aryl boron ester 1h and phenylpropyne 2f produces chiral indene 3hf with a regioselectivity ratio of 9.4:1en_US
