A planar-chiral, C2-symmetric bisazaferrocene ligand is shown to control the stereochemistry of Cu(I)-catalyzed ring expansions of oxetanes to tetrahydrofurans.

Copper complex of (7R,7R')-di(1-t-butyldimethylsiloxy-1-methylethyl)-6,6',7,7'-tetrahydro-5H,5'H-2,2'-bi-1,1'-pyridine (3) was found to be an effective catalyst for asymmetric carbene insertion reaction into the C-O bond of oxetanes.For example, the react
