Synthesis and Application of Bis-Silylethyl-Derived Phosphate-Protected Fmoc-Phosphotyrosine Derivatives for Peptide Synthesis
摘要:
Three Fmoc-phosphotyrosine derivatives with silylethyl-based phosphate protection were synthesized and evaluated for use in peptide synthesis. The stability of these derivatives toward piperidine/DMF (1:4) treatment and their cleavability with TFA solutions were examined. On the basis of these data, the bis[(methyldiphenylsilyl)ethyl]-protected Fmoc-phosphotyrosine derivative or Fmoc-Tyr(PO(3)MDPSE(2))-OH, was shown to be the most suitable candidate for the production of phosphotyrosine peptides. The syntheses of phosphotyrosine peptides including one containing Met and Cys are described.

A highly-stereoselective method (90 % of theZ-isomer) was developed for the Petersonolefination of ketones with nerylacetone (1) as an example. The method is based on the introduction of a PhS group, which is removed after completion of the reaction, at the ketone C(3) atom.
