dc.description.abstract | 本文分為二個主題,依序討論以三氯化銦輔佐共軛烯炔-炔醯胺化合物進行分子內環化反應及二溴化鐵輔佐4-炔醯胺環己-2-烯-1-酮進行分子內麥可加成反應(Michael-Addition),分別得到δ-內醯胺與稠環γ-內醯胺衍生物。 (一) 利用三氯化銦進行輔佐,可以使共軛烯炔-炔醯胺化合物進行分子內環化反應,合成出δ-內醯胺衍生物。此反應的優點是:起始物製備容易、反應條件溫和、不須添加氧化劑及反應時間短。 (二) 利用二溴化鐵輔佐4-炔醯胺環己-2-烯-1-酮,於氮氣回流的條件下進行環化反應,反應先形成keteniminium中間體I,溴陰離子再親核性加成至keteniminium中間體α位置的碳上,接著再進行分子內麥可加成反應,在反應終止後,即可得到稠環γ-內醯胺衍生物。此反應的優點是:具有良好的立體選擇性及在進行環化反應時不須額外添加氧化劑。 關鍵字:炔-炔醯胺、三氯化銦、銦(III)、δ-內醯胺、2-環己烯-1-酮、二溴化鐵、稠環γ-內醯胺 | zh_TW |
dc.description.abstract | This thesis conatins two topics. Indium(III) chloride-assisted cyclization of ynamido-tethered conjugated ene-ynes generated δ-lactam derivatives and iron(II) bromide-mediated Michael-addition of 4-yne-amido-cyclohex-2-en-1-ones yielded bicyclic γ-lactam derivatives. (1) Indium(III) chloride assisted cyclization of ynamido-tethered conjugated ene-ynes furnishes δ-lactams. The reactions feature procedurally simple, producing the products under the mild conditions without additional oxidants and with short reaction time. (2) Treatment of iron(II) bromide with 4-yne-amido-cyclohex-2-en-1-ones under nitrogen at reflux affords bicyclic γ-lactams. Activation of ynamide with FeBr2 gives the keteniminium ion I, which was trapped by a bromide ion at the α-potision to afford intermediate II. Intramolecular Michael-Addition of II gives the bicyclic γ-lactams. The reactions feature excellent diastereoselectivity and producing the products without additional oxidants. Keywords:yne-ynamides、indium(III) chloride、indium(III)、δ-lactams、cyclohex-2-en-1-ones、iron(II) bromide、bicyclic γ-lactams | en_US |
