enantiomers of mandelic acid have each been converted into 1,3-dioxolan-4-one derivatives. Formation of the planar chiral (η6-arene)tricarbonylchromiumcomplexes has enabled an investigation of their potential to promote discrimination between the diastereotopic ortho and/or meta arene hydrogens during lithiation–silylation.
