First Application of the Dakin-West Reaction to Fmoc Chemistry: Synthesis of the ketomethylene tripeptide Fmoc-Nα-Asp(tBu)-(R,S)Tyr(tBu)Ψ(CO-CH2)Gly-OH

International audienceA practical synthesis of a tripeptide containing a ketomethylene isostere, suitably protected for introduction in Fmoc SPPS, has been carried out for the first time in Fmoc chemistry by using a modified Dakin-West reaction
