過去三十年來,自由基在有機合成反應中扮演著相當重要的角色,由最初的有機型自由基引發劑,經由物理性或化學性的作用生成自由基,到近年來金屬氧化性的反應。金屬氧化性反應是藉由過渡金屬含有多個氧化態的方式,使反應物生成自由基,並進一步的去做合環反應。
本篇論文將使用乙醯丙酮酸銅(Ⅱ)作為還原劑,鄰二氮菲作為配位基,對N-苄基-2-溴-2-甲基-N-苯基丙醯胺類化合物與2-溴-2-甲基-N-(4-甲苯基)-N-(苯磺醯基)丙醯胺類化合物進行金屬還原性自由基反應生成吲哚-2-酮類化合物與2-甲基-2-苯基-N-(4-甲苯基)丙醯胺類化合物。
According to the recent literatures, most of the methods use the radical initiator or metal to generate radical group. Afterward the radical group can undergo the addition reaction with unsaturated bond of the reactant, then the reactant do the cyclization to synthesis indol-2-one further. In this thesis, we synthesis the compounds which have a bromide group as reactants. We use the copper(II) acetylacetonate as an oxidant, and phenanthroline as a ligand to react with our reactant. The reactant may generate stably radical, and then that do cyclization reaction directly. The results show that we can use this method to synthesize a variety of indol-2-one derivatives, and this method is applicable to a variety of functional groups.
