lactam-type 2-iodobenzamide catalysts, 8-iodoisoquinolinones 8 (IB-lactam) and 9 (MeO-IB-lactam), were developed. These catalysts have a conformationally rigid 6/6 bicyclic lactam structure and are more reactive than the previously reported catalysts 2-iodobenzamides 4 (IBamide) and 5 (MeO-IBamide) for the oxidation of alcohols. The lactam structure could form an efficient intramolecular I---O interaction
开发出了第一种内酰胺型 2-
碘苯甲酰胺催化剂 8-
碘异喹啉酮 8(IB-内酰胺)和 9(MeO-IB-内酰胺)。这些催化剂具有构象刚性的 6/6 双环内酰胺结构,并且比之前报道的催化剂 2-
碘苯甲酰胺 4 (IBamide) 和 5 (MeO-IBamide) 的醇氧化反应活性更高。内酰胺结构可以形成有效的分子内I---O相互作用,具体取决于内酰胺环的大小。
