The Uses of 2-Chloro-3-pyridylboronic acid
Reactant for:
- Synthesis of Et canthinone-3-carboxylates from Et 4-bromo-6-methoxy-1,5-naphthyridine-3-carboxylate via a Pd-catalyzed Suzuki-Miyaura coupling and a Cu-catalyzed amidation reaction
- Preparation of arylmethylpyrrolidinylmethanols and amine derivatives via reaction with MIDA followed by Suzuki reaction with halides or amination with amines
- Preparation of arylazabicyclooctane derivatives as potential arginine vasopressin receptor antagonists
- Regioselective preparation of halo-oligopyridines and oligopyridines by the Suzuki-Miyaura cross-coupling reaction
