Abstract
A series of 10 new carbohydrate-substituted bipyridines were prepared from 2, 2′- bipyridine-3, 3′-dicarboxylic acid, itself easily available from ortho-phenanthroline. As a preliminary exploration of their use as chiral ligands, Cu (II)-catalysed asymmetric electrophilic fluorination of model β-ketoesters using these simple and easily accessible chiral bipyridines was studied. Only modest enantioselectivity was observed in this ...
