Application

4-Hydroxyphenylboronic acid can be used as a reactant in:
  • Suzuki-Miyaura coupling and Stille coupling reactions.
  • Palladium-catalyzed aminocarbonylation and cross-coupling reactions.
  • Suzuki reaction for preparation of bio-supported palladium nanoparticles as phosphine-free catalysts.
  • Cu2O-catalyzed aerobic oxidative cross-coupling of tetrazoles.

It can also be used to prepare/promote:
  • PDK1 inhibitory activity (cancer cell growth, survival, and tumorigenesis inhibitor).
  • Rod-like dendronized polymers containing G4 and G5 ester dendrons via macromonomer approach by living ROMP.
  • Estrone-derived cyclopamine analogs as Sonic Hedgehog signaling inhibitors for anti-cancer chemotherapeutics.
  • Enzymatic inhibitors for the treatment of Gram-negative bacterial infections.
  • Oligoarenes by Suzuki-Miyaura palladium-catalyzed cross-coupling.
