The first catalytic stereoselective approach to prepare multiple substituted cyclic nitriles by means of a novel metal‐free intramolecular carbocyanation strategy has been developed, which provided an efficient protocol to construct densely functionalized diastereoenriched pyrrolo[2,1‐a]isoquinoline derivates under mild reaction conditions (up to 20/1 d.r., 98 % yield).
已经开发出了第一种通过新型的无金属分子内碳氰化战略制备多个取代的环腈的催化立体选择方法,该方法为在温和的反应条件下构建密集官能化的非对映异构的吡咯并[2,1- a ]异喹啉衍生物提供了有效的方案。(高达20/1 dr,98%的产率)。
