decarbonylative coupling between cyclobutanones and alkenes that proceeds by C−C activation and provides a distinct approach to a diverse range of saturated bridged cyclopentane derivatives. In this reaction, cyclobutanones serve as cyclopropane surrogates, reacting in a formal (4+2−1) transformation. To demonstrate the efficacy of this method, it was applied in a concise synthesis of the antifungal drug Tolciclate
在此,我们报道了环丁酮和烯烃之间的分子内铑催化脱羰偶联,该偶联通过 C−C 活化进行,并为各种饱和桥联环戊烷衍生物提供了一种独特的方法。在此反应中,环丁酮充当环丙烷替代物,以形式 (4+2−1) 转化进行反应。为了证明该方法的有效性,将其应用于抗真菌药物 Tolciclate 的简明合成中。
