Modular bipyridine ligands coupled with Cinchona alkaloids for Cu(II)-catalyzed asymmetric Henry reactions

Article abstract of DOI:10.1016/j.tetasy.2013.05.009

A new series of bipyridine ligands coupled with Cinchona alkaloids were prepared in relatively high yields in only one step starting from commercially or readily available materials, and have been developed as chiral ligands for copper(II)-catalyzed asymm
