dc.description.abstract本論文利用一價銠金屬與本實驗室開發之掌性雙環[2.2.1]雙烯配基L1e的催化系統,使各式烯醇醚基三氟硼酸鉀鹽試劑 53a‒f與芳香基亞胺10a‒o進行不對稱催化加成反應,在100 oC下以甲苯作為溶劑,添加100 wt%研磨過分子篩 (MS 4Å),反應六小時,可合成出具有高鏡像選擇性的新型掌性烯丙基胺骨架之產物34,其產率為21%到83%,鏡像超越值為94%到>99.5% ee。 在合成應用上,利用合成出的新型掌性烯丙基胺化合物34ae,經由簡單的官能基轉變,就可以合成出市售藥物 (S)-Dapoxetine (60)。zh_TW
dc.description.abstractThis thesis describes the asymmetric synthesis of optically active amines bearing enol ethers. In the presence of 5.0 mol% of the Rh(I) catalyst comprising chiral diene ligand L1e, the enantioselective addition of potassium enol ether trifluoroborates (53a‒f) to aldimines bearing N-Ts protecting groups afforded the desired allylic amines in 21– 83% yields with 94–>99.5% ee. The method was applied to the total synthesis of (S)-Dapoxetine (60).en_US
