Surprisingly, the simplest method possible for o-azaxylylene production, base-induced elimination of hydrogen chloride from amide or sulfonamide derivatives of o-(chloromethyl)aniline, has never been reported. This powerful approach provides easy and stereoselective access to polycyclic hydroquinolines, as shown for an example in Equation (1).
令人惊讶的是,邻(氯甲基)苯胺的酰胺或磺酰胺衍生物通过碱诱导消除氯化氢来制备邻氮杂亚二甲苯的可能最简单的方法从未被报道过。这种强大的方法为多环氢喹啉提供了简便且立体选择性的合成途径,如式(1)中的示例所示。
