Ni-Catalyzed Protecting Group Free Diphenic Acid Analog Synthesis.

Severe side effects and drug resistance are major drawbacks of Pt-based chemotherapy in clinical practice, leading to the search for new Pt-based drugs through the tuning of coordination ligands. Therefore, seeking appropriate ligands has attracted significant interest in this area. In this study, we report a Ni-catalyzed coupling strategy for the divergent synthesis of diphenic acid derivatives and the application of these newly prepared acids in Pt(II) agent synthesis.
