| dc.description.abstract | 中文摘要: 本論文利用一價銠金屬和雙環 [2.2.1] 掌性雙烯配基 (L1a) 形成之錯合物為催化劑,以甲苯當溶劑加熱至100 °C的反應條件下,催化各種不同的烯丙基三氟硼酸鉀鹽試劑 27a–e 與芳基醛亞胺 30、33 進行不對稱1,2-加成反應,合成出一系列高鏡像選擇性的高烯丙基胺 (homoallylic amines) 化合物 31、34–38,其產率有24–90%,鏡像超越值為67–98% e.e.,而非鏡像異構物比值最高可達10:1。 利用建立出來的掌性化合物 31f 作為起始物,將不同的官能基骨架相續接上後合環,及可合成出天然物(S)-Crispine A。 | zh_TW |
| dc.description.abstract | Abstract: In the presence of 3.0 mol% of the Rh(I) catalyst comprising chiral diene ligand L1a, the asymmetric addition of potassium allyltrifluoroborates (27a–e) to aldimines bearing N-Ts and N-Ns protecting groups afforded the desired homoallyl amines in 24–90% yields with 67–98% e.e. with up to 10:1 diastereselectivity. The method was applied to the total synthesis of Crispine A. | en_US |
