Addition of carbon-based nucleophiles to Fmoc-protected acyl iminium ions.
Weakly basic carbon nucleophiles add efficiently to a Fmoc-protected N,O-acetal compound. The new reactions highlight the compatibility of the Fmoc protecting group with moderately basic reaction conditions and should serve as a model for the development of more efficient syntheses of Fmoc-protected amino acids.
