9-Fluorenylmethyloxycarbonylation (Fmoc) Reagents [Protecting Reagents]

　9-Fluorenylmethyloxycarbonyl (Fmoc) group is one of the most commonly used protecting groups for amino groups in solid phase peptide synthesis as well as the Boc group. It is readily deprotected by secondary amines such as piperidine while it is stable under acidic conditions. Therefore, when a molecule contains the Fmoc group and the BOC group, only the BOC group can be selectively removed under acidic conditions.
