New efficient method for the synthesis of chiral 2,2?-bipyridyl ligands

An efficient preparation of chiral 2,2?-bipyridines was developed. Compound 1 was synthesized in 54% yield for three steps starting from 2,6-dibromopyridine. In this synthesis, only catalytic amounts of metals were used in the asymmetric reduction and homo-coupling reaction steps. The total yield and simplicity of experimental procedures were much improved compared with those of the previous report. Other chiral 2,2?-bipyridines were similarly synthesized with high efficiency.
