Application

6-Chloro-3-pyridinylboronic acid can be used:
  • To prepare biologically significant 3-arylcoumarins by reacting with 3-chlorocoumarin through Suzuki reaction.
  • As a substrate in the synthesis of 11-(pyridinylphenyl)steroid with progesterone agonist/antagonist profile.
  • As a substrate in the preparation of α- secondary and tertiary pyridines by the reaction of pyridotriazoles with boronic acids.
  • As a substrate in the palladium-catalyzed α-arylation of saturated cyclic amines and N-methyl amines.
