第一章 我們發展了經由金金屬催化劑可以使炔醯胺和各種不同種類的丙烯醇和丙炔醇在室溫下進行各種不同加成反應,其中包括了克萊森重排形式的產物,以及進行1,4加成形式的產物,還有先進行1,4加成在進行合環反應的產物。 第二章 經由鋅催化劑可以使Chloramine-T活性提高,在與帶有可以共振雙鍵的炔醯胺和Chloramine-T,在溫和以及室溫的條件下進行氯胺化,得到高產率的雙氯亞胺形式的產物,其中此產物含有一個一級的碳氯鍵及一個二級的碳氯鍵,都可以應用於多樣的取代反應,容易與其他親核試劑進行反應,便可得到更多樣的化合物。
Chapter 1 We developed the gold-catalyzed reaction with allylic alcohol and propargyl alcohol delivering variety of product such as Claisen rearrangement’s type product, 1,4 addition’s type product and undergo cyclization followed by 1,4 addition’s type product. Chapter 2 An efficient Zinc catalysis enhances the reactivity of the Chloramine-T, and Chloramine-T react with the ynamides which has the vibration’s olefin. The reaction will undergo the chloroamination of ynamides with Chloramine-T at room temperature. The reaction will get the Polyhalogenaldimes in the moderate to good yields. The products will include one primary C-Cl bond and one secondary C-Cl bond, with these good leaving group, it can promote their interaction with divergent nucleophiles to form numerous novel compounds.
