Application

3-Hydroxyphenylboronic acid (3-HPBA) can be used as a reagent:
  • In Suzuki-Miyaura coupling reactions with aryl halides for the formation of C-C bond in the presence of Pd catalyst.
  •  To synthesize boron/nitrogen-doped polymer nano/microspheres by hydrothermal polymerization with formaldehyde and ammonia.      
  • To prepare carbon quantum dots based on 3-HPBA as selective fructose sensor.     
  • In the development of modified electrodes for electrochemical biosensors.

As a continuation of our previous report (J. Comb. Chem.2010, 12, 548-558), we accomplished the diversity-oriented synthesis of polyheterocyclic small-molecule library with privileged benzopyran substructure. To ensure the synthetic efficiency, we utilized the solid-phase parallel platform and the fluorous-tag-based solution-phase
