Multi-substituted benzothiophene skeleton is an important synthetic intermediate, and the insertion reaction of diazo compounds catalyzed by transition metals provides a practical method for the synthesis of such compounds. This article uses Rhodium as catalyst to achieve the insertion reaction between diazothiooxindoles and pyridine carbonate compounds, providing a series of multi substituted benzothiophene compounds with good yield. This reaction has the characteristics of mild conditions and practical efficiency. At the same time, biological activity tests were conducted on several cell lines using the product, including NIH-3T3, B16-F10, 4T1 and HCT116.

Key words: multi-substituted benzothiophene, diazo compounds, metal catalysis
