dc.description.abstract本論文主要研究分為兩大部分: 第一部份:α,β-不飽和雙酮化合物 79 作為親核性試劑,與 1,3-茚二酮反應,以 Michael-Michael-acetalization 反應建構雙環橋形 [3.3.1] 九員環骨架化合物。 第二部分:製備新穎的 Wittig 試劑以合成多官能基取代的烯類化合物 第一部分,經由 α,β-不飽和雙酮化合物 79 和 1,3-茚二酮的有機不對稱反應,建構具有四級碳的多取代雙環橋形 [3.3.1] 九員環骨架化合物 81 ,此反應的單一鏡像異構物,產率為 10-84%,鏡像超越值可高達 85%。 (產物尚未解出絕對立體組態,先以相對立體結構表示) 第二部分,利用活性烯類與三丁基膦合成新穎的 Wittig 試劑後,與 Michael 受質 131 及醛類分子 132 反應,經由高立體選擇性之 Wittig 反應合成出具有多取代烯類產物 133,產率為 43-92%。zh_TW
dc.description.abstractThis thesis is divided into two parts: Part 1. Synthesis of bicyclo[3.3.1]nonane derivatives via organocatalytic asymmetric double Michaal-acetalization reaction with α,β-unsaturated 1,3-diketones and 1,3-indandiones Part 2. Synthesis of multi-functional alkenes via Wittig Reaction with a new-type of phosphorus ylide In the first part, a series of novel bicyclo[3.3.1]nonane derivatives with a quaternary stereocenter were synthesized via organocatalytic asymmetric double Michael-acetalization reaction of α,β-unsaturated 1,3-diketones 79 and 1,3-indandiones 80. In the second part, we have developed a new type of Wittig reagent from PBu3 and Michael acceptors 131, which could be utilized in the Wittig reaction with a variety of aldehydes 132 to synthesize multi-functional alkenes 133 with excellent stereo-selectivity.en_US
