detailed procedure for successive regioselective lithiations of furo[2,3-c]pyridine is described by using n-BuLi and the [n-BuLi/LiDMAE] superbase. Several polysubstituted furo[2,3-c]pyridines have been efficiently synthesized and some of them were engaged in Pd- or Ni-catalyzed coupling reactions leading to 2,2′- or 7,7′-bifuro[2,3-c]pyridine ligands.
