Abstract: | Electrophilic fluorinations of lithiated bis-lactim ethers derived from cyclo-L-AP4-D-Val] allow a direct access to alpha-monofluorinated phosphonate mimetics of naturally occurring phosphoserine and phosphothreonine, in enantiomerically pure form and suitably protected for solid-phase peptide synthesis. |
