Boc group protector
WebIn Boc chemistry, the commonly used protecting groups are Boc, 2,4-dinitrophenyl (Dnp), Tos and benzyloxymethyl (Bom). The sidechain Boc group is removed when the N-terminal Boc group is removed, so Boc-His(Boc)-OH is mainly useful to prepare short peptides or to introduce a histidine residue near the N-terminal of a peptide. WebBoc Protecting Group Before the Fmoc group became popular, the t-Boc group was commonly used for protecting the terminal amine of the peptide, requiring the use of …
