dc.description.abstract利用□喃-丙二烯胺基之分子內Diels-Alder反應來合成四氫異□□衍生物 學生 : 杜 文 平 指導教授 : 吳 獻 仁 博士 國立交通大學應用化學所 中文摘要 以□喃為二烯基、以丙二烯胺基作為親二烯基利用分子內Diels-Alder反應的方法,再以化學轉換即可以成功地合成出tetrahydroisoquinoline的骨架11,13,16。 利用氧原子與氮原子來研究雜異原子對於分子內Diels-Alder反應之影響性。當以氮原子作為二烯基與丙二烯胺基之橋樑時,發現□喃環5號位置上之取代基為氫與甲基時,可以直接得到環化加成產物6與23。如果取代基為硫代甲醚基時,以氮原子作為二烯基與丙二烯胺基之橋樑,以氧原子作為二烯基與丙二烯醚基之橋樑時,均無法直接得到環化加成產物,而都是得到開環後的產物35,42,60。 在本論文的研究中,均沒有重排反應的發生。綜合本實驗室以前之研究,因此初步認為重排反應與雜異原子無關,不過尚待將來再繼續討論。zh_TW
dc.description.abstractSynthesis of Tetrahydroisoquinolines via Intramolecular Diels-Alder Reaction of Furans with Allenylamine Student : Du, Wen-Pine Advisor : Dr. Wu, Hsien-Jen Institute of Applied Chemistry National Chiao Tung University Abstract The skeleton of tetrahydroisoquinoline 11, 13, 16 via intramolecular Diels-Alder reaction of furan diene with propargyl amine was synthesized, successfully. And we also study the influence of hetroatom to intramolecular Diels- Alder reaction. In the series of nitrogen, when the substituent is hydrogen or methyl group, we can isolate the cycloadduct 6 and 23, directly. In the series of nitrogen and oxygen, when the substituent is methylthio group we all isolate ring opening product 35, 42, 54, directly, and we don’t obtain the cycloadduct. In here, we propose a proper machanism of intramolecular Diels-Alder reaction product, and use methylsulfonyl and methylsulfinyl group, 62 and 67 to prove the machanism. But we don’t obtain the positive evidence. We only obtain the elimination product.en_US
