N-Containing heterocycles are important scaffolds due to their ubiquitous presence in bioactive compounds. Their synthesis has been considered as an important research field. In this work we report the access to 6- and 7-membered rings via a photoinduced strategy. To our knowledge, this work represents the first exemple of photo-induced 7-endo-trig cyclization with N-centered radicals.
含氮杂环是重要的支架,因为它们普遍存在于
生物活性化合物中。它们的合成被认为是一个重要的研究领域。在这项工作中,我们报告了通过光诱导策略访问 6 元和 7 元环。据我们所知,这项工作代表了具有N中心自由基的光诱导 7- endo - trig 环化的第一个例子。
