A variety of N-vinyl and N-aryl amides were converted to the corresponding pyridine and quinoline derivatives, respectively. Amide activation and nucleophilic addition of copper(I) (trimethylsilyl)acetylide efficiently provided the desired alkynyl imines. Ruthenium-catalyzed protodesilylation and cycloisomerization of these imines gave the corresponding azaheterocycles.
各种 N-乙烯基和 N-芳基酰胺分别被转化为相应的吡啶和喹啉衍生物。酰胺活化和亲核加成铜(I) (三甲基硅烷基)乙酰化物能有效地提供所需的炔亚胺。在钌催化下,这些亚胺发生原代甲硅烷基化和环异构化反应,生成相应的杂杂环。
