industries. Hence, rapid and efficient construction of fluorinated heterocycles remains highly demanded. Herein, a difluoroalkylative carbonylative cyclization of unactivated alkenes and ethylene gas enabled by palladium catalysis has been developed for the first time toward the synthesis of α-carbonyl difluoro-modified glutarimides. This procedure can also be applied to the synthesis of GeMigliptin which
氟化杂环化合物在制药和农用化学工业中发挥着至关重要的作用。因此,仍然迫切需要快速有效地构建氟化杂环。在此,首次开发了通过钯催化实现的未活化烯烃和乙烯气体的二氟烷基化羰基化环化反应,用于合成 α-羰基二氟修饰的戊二酰亚胺。该程序也可应用于 GeMigliptin 的合成,GeMigliptin 是一种批准用于治疗 2 型糖尿病的药物。
