摘    要:以手性磷酸作为催化剂,研究了3-亚甲基异吲哚-1-酮与吲哚的不对称傅克烷基化反应。通过对催化剂、溶剂及反应温度等条件的优化,发现在室温条件下,以(S)-1-萘基取代的手性磷酸CPA-5为催化剂,在二氯甲烷溶剂中,反应可以获得51%N对映选择性。在此条件下,考察了吲哚的取代基效应,获得优秀的反应收率和39%~64%的ee值。

关 键 词:手性磷酸  不对称傅克反应  吲哚  烯胺

Abstract:Friedel-Crafts alkylation reaction of 3-methylene-isoindol-1-one and indoles catalyzed by chiral phosphoric acid was studied.. With the optimization of catalyst, solvent and reaction temperature, the optimum catalyst was (S)-1-naphthyl replaced CPA-5 chiral phosphoric acid, optimum solvent was dichloromethane. The reaction could obtain 51% stereoselectivity under the room temperature. Under these conditions, the substituent effect of indole was investigated, good reaction yield and 39%-64% ee were obtained.
Keywords:chiral phosphoric acid  asymmetric Friedel-Crafts reaction  indole  enamine
