The reaction between lithiated anions derived from N-substituted (diet
hyl-beta-ketophosphono)-alpha-aminoacids and aldehyde compounds gives
direct access to unsaturated derivatives of alpha-aminoacids. Applicat
ion to the glucidic serie leads to an attractive route to pseudoglycop
eptide precursors.
