The Horner–Wadsworth–Emmons reactions of 2-fluoro-2-diethylphosphonoacetic acid with 2-{[(triisopropylsilyl)oxy]methyl}cyclopentanone (2-TOM-cyclopentanone) using methylmagnesium chloride furnished the corresponding tetra-substituted fluoroolefin in a Z -selective manner ( E / Z = 9:91). A facile synthesis of rac - N -Cbz-Gly-Ψ[( Z )-CF C]-Pro-OH as a dipeptide isostere was achieved based on the Z -selective Horner–Wadsworth–Emmons reaction. [ABSTRACT FROM AUTHOR]
