Olefination of carbon–heteroatom double bonds is a powerful approach to access highly functionalized olefins. An approach is reported here that uses air-stable and commercially available ruthenium alkylidenes to promote C=N/olefin ring closure. The enabling strategy for this reaction is the use of hydrazones and oximes as readily accessible substrates that preferentially react with ruthenium alkylidenes
碳-杂原子双键的烯化是获得高度官能化烯烃的有效方法。此处报告了一种方法,该方法使用空气稳定且市售的亚烷基钌来促进 C=N/烯烃环闭合。该反应的可行策略是使用腙和肟作为易于获得的底物,即使在羰基存在的情况下,它们也优先与亚烷基钌反应。
