A practical synthetic approach to the difluoro-substituted bicyclo[1.1.1]pentanes was developed. The key step was an addition of difluorocarbene (:CF) to electron-rich bicyclo[1.1.0]butanes by the CFTMS/NaI system. The obtained difluoro-bicyclo[1.1.1]pentanes are suggested to be used as saturated bioisosteres of benzene rings for the purpose of drug discovery projects.
开发了一种实用的二氟取代双环[1.1.1]戊烷的合成方法。关键步骤是通过 CFTMS/NaI 体系将二氟卡宾 (:CF) 加成到富电子的双环[1.1.0]丁烷上。所得到的二氟双环[1.1.1]戊烷被建议用作苯环的饱和生物等排体，用于药物发现项目。
