摘要
The Horner-Wadsworth-Emmons reactions of 2-fluoro-2-diethylphosphonoacetic acid with 241(triisopropylsilyl)oxy]methyl)cyclopentanone (2-TOM-cyclopentanone) using methylrnagnesium chloride furnished the corresponding tetra-substituted fluoroolefin in a Z-selective manner (E/Z = 9:91). A facile synthesis of rac-N-Cbz-Gly-Psi[(Z)-CF=C]-Pro-OH as a dipeptide isostere was achieved based on the Z-selective Horner-Wadsworth-Emmons reaction. (C) 2014 Elsevier Ltd. All rights reserved.
