(NHC) ligands has been developed. The resulting ligands have restricted flexibility and high steric demand. Preliminary studies have shown these ligands to give high levels of asymmetricinduction in the copper-free allylicalkylation of cinnamyl bromide.

to realise the first example of asymmetric radical conjugate addition to α,β-unsaturated anhydrides and esters. The chemistry, mastered by a chiral isothiourea organocatalyst, enables the synthesis of enantioenriched pyrrolidinones, with application to the synthesis of biologically-active γ-amino butyric acids.
