Chiral recognition in the reaction of the enolate derived from [(η5-C5H5)Fe(CO)(PPh3)CO CH2OCH2Ph] with cis- and trans-2,3-epoxybutane: The stereoselective synthesis of cis and trans-βγ-disubstituted-γ-lactones
Davies SG., Middlemiss D., Naylor A., Wills M.
The reaction between the enolate derived from [(η5-C5H5)Fe(CO)(PPh3)CO CH2OCH2Ph] and cis- and trans-2,3-epoxybutane proceeds with a high degree of chiral recognition between the reagents (10:1) to give products which may be converted to β,γ-dimethyl-γ-lactones possessing trans- or cis- stereochemistry. © 1989.
