Chemical name: N-alpha-(9-Fluorenylmethyloxycarbonyl)-L-aspartic acid beta-(5-butylnon-5-yl) ester // Synonyms: Fmoc-Asp(OBno)-OH, N-alpha-Fmoc-(O-5-(n-butyl)-non-5-yl)aspartic acid, (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-((5-butylnonan-5-yl)oxy)-4-oxobutanoic acid
|Molecular weight:||537,70 g/mol|
An extremely effective derivative for minimizing aspartimide formation during Fmoc SPPS of Asp-containing peptides. The bulky OBno protecting group provides considerably more protection against the formation of aspartimide-related by-products than the commonly used OtBu and OMpe groups.
Preventing aspartimide formation in Fmoc SPPS of Asp-Gly containing peptides - practical aspects of new trialkylcarbinol based protecting groups. Raymond Behrendt, Simon Huber, Peter White; J. Pept. Sci. 2016; 22(2):, 92-97. DOI:10.1002/psc.2844
