Application
- Synthesis of a burkholdine analogue containing β-hydroxytyrosine: This study discusses the synthesis of a burkholdine analogue, utilizing Fmoc-Asn(Trt)-OH as part of the solid support loading process (Kato et al., 2019).
General description
Fmoc-Asn(Trt)-OH has good solubility properties in most organic solvents, and its use has been shown to result in significantly purer peptides than other derivatives used for the introduction of Asn [1,2]. Coupling can be performed by standard procedures. The trityl group is normally removed by 95% TFA in 1-3 hours, with no alkylation of Trp residues. When Asn(Trt) is the N-terminal residue, the reaction time may need to be extended to ensure complete deprotection [3].
