A dearomative strategy to regioselectively modify arenes using a "diene" synthon within aromatic rings provides access highly functionalized heterocycles from abundant feedstocks and represents an alternative synthetic approach besides traditional cross-coupling C-H functionalization methodologies. In this study, we present efficient method for selectively introducing boron onto quinolines through hydroboration easily accessible stable phosphine-ligated borane complexes. The vicinal 5,6- conjugate 5,8-hydroborated products could be obtained by modifying the phosphine ligand. Drawing inspiration diverse organoboron transformations, these building blocks were diversified range of downstream functionalizations, providing modular pathways skeletal modifications variety challenging heterocycles.
