ChemInform Abstract: An Original One-Pot Synthesis of 5-(4-Pyridyl)-benzo(c)-2,7- naphthyridine as Key Intermediate in the Synthesis of Amphimedine by Metalation Connected with Cross-Coupling Reaction.
Under very mild conditions, functionalized benzoxaborole derivatives were prepared in good to excellent yields via a palladium-catalyzed Miyaura borylation reaction of readily available unprotected o-bromobenzylalcohols, and bis(pinacolato)diboron (B2pin2) without the assistance of an acid.
