Application

3-Pyridineboronic acid neopentylglycol ester can be used as a reactant:
  • To synthesize N-alkyl-3-boronopyridinium salts by reacting with corresponding alkyl halides.
  • In the ruthenium-catalyzed diastereoselective C-H bond α-arylation of cyclic amines.
  • To prepare 2-(3-pyridyl)benzoxazole by reacting with benzoxazole via copper-catalyzed oxidative arylation reaction.
  • In the Suzuki-Miyaura cross-coupling reaction.
