Enantioselective oxidative coupling of the titanium enolate of 3-phenylacetyl-2-oxazolidinone.
Enantioselective oxidative coupling of titanium and ytterbium enolates of 1 bound to chiral diol, e.g., TADDOL 6, and bisoxazoline ligands with ferrocenium cation as oxidant affords dimers 2 with moderate to good enantioselectivities. Reaction: see text.
