Fluorous tags are perfluoroalkyl modified versions of traditional protecting groups familiar to synthetic organic chemists. Conceptually they are very similar to solid phase tags, but fluorous tags and fluorous tagged substrates are soluble in most organic solvents, such as DMF, THF, CH2Cl2, etc. This provides some distinct advantages over solid phase tagging strategies including solution phase kinetics, complete control of reaction stoichiometry, and the ability to monitor reactions easily using traditional analytical techniques, including TLC, NMR, GC, LC/MS, and IR. The fluorous tagged materials are easily separated from non-tagged components by F-SPE. Fluorous tags have been used in a variety of total, parallel, and mixture syntheses (1-3).

F-Cbz-Osu
|
 |
|
|
|
|
F-Cbz-OSu is the fluorous equivalent of benzyloxycarbonyl oxysuccinimide (Cbz-OSu) used primarily in the protection of amino groups in peptide synthesis or multi-step organic synthesis. Deprotection of the F-Cbz group is achieved under the same conditions as traditional Cbz such as hydrogenation or hydride reduction. F017008, the C8F17 analog of F-Cbz has appropriate fluorine content for the tagging of diverse organic molecules and is recommended for natural product or medicinal chemistry synthesis in combination with fluorous solid phase extraction. The other F-Cbz homologs are useful in fluorous HPLC and fluorous mixture synthesis.
