approach for an efficient access to cyclic β-amino acids widely found in bioactive small molecules and peptidic foldamers. Our method involves addition of the remote γ-carbon atoms of α,β-unsaturated imines to enals by iminium organic catalysis. This highly chemo- and stereo-selective reaction affords cyclic β-amino aldehydes that can be converted to amino acids bearing quaternary stereocenters with
the success of the phospha-Michael reaction between β-CF3-β,β-disubstituted enones and diarylphosphine oxides, providing an access to biologically relevant γ-ketophosphine oxides bearing a sterically highly congested CF3- and P(O)-tetrasubstituted carbon center. More importantly, the resulting products could be further transformed into densely functionalized γ-ketophosphine oxides containing a CF3- and

Silyl enolethers (1) react with the phenylthio(methoxycarbonyl)alkyl chlorides (2) in the presence of Lewis acids to give good yields of the γ-ketoesters (3); oxidative and reductive desulphurisations give the saturated (4) and unsaturated (5 or 6) γ-keto esters, respectively.
