General description
An excellent derivative for minimizing aspartimide formation during Fmoc SPPS of Asp-containing peptides. The bulky OEpe protecting group offers considerably more protection against the formation of aspartimide-related by-products than the commonly used OtBu and OMpe group. The combination of Asp(OEpe) and the use of 1 M Oxyma Pure in DMF for Fmoc removal results in minimal aspartimde formation.
