回顧過去三十年,利用氧化性自由基反應形成碳-碳鍵結的方式,已成為一種有效的合成策略;此方法不同於還原性自由基所進行的反應,其產物擁有高度官能基化的特色。
對於氧化β-雙羰基化合物而言,醋酸錳(Ⅲ)是一個常見的單電子氧化劑;其所形成的自由基中間體能夠有效地進行分子間及分子內環化反應。本實驗室則是針對萘醌化合物的親電性自由基反應深感興趣。
此論文共分為兩部分:
(1) 2-苯甲醯-1,4-萘醌化合物與1,3-雙羰基化合物之氧化性自由基反應。
(2) 3-苯甲基-2-乙酸乙酯基-1,4-萘醌化合物之分子內氧化
性自由基反應。
Over the past thirty years, oxidative radical reaction have become a valuable method for the formation of carbon-carbon bonds. This method differs from reductive free radical reactions, and it leading to more highly functionalized products.
Manganese(Ⅲ) acetate is an extensive one-electron oxidant for the oxidation of β-dicarbonyl compounds. The radical intermediate which created by Mn (Ⅲ) can undergo efficient intermolecular and intramolecular cyclizations. In our laboratory, we are interested in electrophilic free radical reaction of quinones derivatives.
Thesis describes our studies on :
(1) Oxidative free radical reaction between 2-Benzoyl-[1,4] naphthoquinones and 1,3-dicarbonyl compounds.
(2) The intramolecular cyclization of ethyl (3-benzyl-1,4- dioxo-1,4-dihydro-naphthalen-2-yl) acetates.
