本論文中,以探討不同類型醣類化合物的合成為主。在近年來,醣類化學逐漸受到重視,除了發現此類分子是細胞間作用的媒介之外,在藥物的開發上,也佔有很重要的地位。但在傳統的醣類合成上,受到反應條件嚴苛及選擇性的問題影響,以致許多含醣分子的合成較為困難,本論文即分別針對以醣類為主的數種化合物進行合成的改進。 在選擇的幾種醣類化合物中,有生物體內天然的醣類配位基,如海膽卵子表面的2,5聚唾液酸,此為受精作用中不可或缺的媒介,合成此2,5聚唾液酸利用一完全In this thesis, new methods for the synthesis of several different types of glyco-conjugates were developed. The target including natural glyco-conjugated ligand, drug mimetic and derivatives. 2,5-neuraminic acid was chosen as the first target. This glycol-conjugate was a very important signal transductor during fertilization of the sea urchin. Here, an amide bond formation reaction was used to construct the 2,5-neuraminic acid dimer. By this method, glycosidic bond was formed through an exclusive目錄 i 圖目錄 iii 表目錄 iv 簡寫表...

鑒於日益嚴重的細菌抗藥性,設計新的抗生素已是刻不容緩的議題。其中,因細菌細胞壁轉醣酶(TGase)不存在於哺乳類生物體內,但易於進出細菌且又尚未發現任何抗藥性的特性,此議題被認為是個有潛力的藥物目標。...
