Diastereoselective synthesis of fluorinated, seven-membered β-amino acid derivatives via ring-closing metathesis

(Matrix presented) Cis and trans seven-membered γ,γ -difluorinated β-amino acid derivatives (III) have been prepared with a sequence that starts with imidoyl halides (I), which are condensed with suitable ester enolates to give intermediates (II). These,
