“…Diester of 4-Chloro-3, 5-dimethylphenylphosphate (4-CDMPP) is synthesized by the method of Auger and Dupius [7] and recrystalysed by absolute EtOH. The compound was fully characterized by IR spectrum at different strengths of OHions, were used to study the rate enhancement at different pH (as for pH 8 -3.9×10 -3 mol dm -3 , for pH 9 -20.8×10 -3 mol dm -3 , for pH 10 -43.8×10 -3 mole dm -3 ) with different concentrations of CTABr (Cetyltrimethyl ammonium bromide).…”

The rate enhancement depends on the hydrophobicity of the nucleophile. The micellar catalyzed reaction between bis-4-chloro-3,5-dimethylphenylphosphate ester and hydroxide or hydroperoxide anions has been examined in buffered medium (pH 8-10). First order rate constant (K ψ) for the reaction of hydroxide ion with bis-4-CDMPP go through maxima with the increasing concentration of cetyltrimethylammoniumbromide (CTABr). Micelles of CTABr very effective catalyst to the reactions of phosphate diesters. Rate constants measured with OH 2 ions are approximately twice and thrice than that of OHions in presence of CTABr.

“…In the 1870s a method was developed for the synthesis of chlorophosphate esters52, 53 (Scheme ).This reaction scheme was later used to prepare diphenyl phosphorochloridate, which can be used to phosphorylate compounds containing a hydroxyl group, and the phenyl protecting groups subsequently removed by hydrogenation 54, 55. This reagent was used for the synthesis of glyceraldehyde phosphate 56, 57.…”

The synthesis of phosphopeptides

et al. 2001

Phosphorylation and dephosphorylation are key events in protein expression and regulation and in signal transduction. Phosphopeptides are very useful reagents for the study of these processes, and have been used to great advantage in the study of phosphatase substrate specificity, SH2 domain ligand specificity, and protein–protein interactions. Furthermore, the advent of cell‐permeable peptide carriers, such as those from the antennapedia homeodomain and the HIV TAT transcription factor, has allowed the study of intracellular events, thus underscoring the utility of these reagents. In this paper we review methods for the synthesis of phosphopeptides with the emphasis on the preparation of phosphoamino acid building blocks. © 2001 John Wiley & Sons, Inc.
