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-thiol is the solution phase equivalent of polymer-bound thiol and has been used as fluorous tags in parallel synthesis. F-thiol has also been used as a scavenger for various electrophiles and as deprotecting agent for 2-nitrobenzenesulfonamides. F017023 has the appropriate fluorine content to be retained on F-SPE cartridges for easy separation.
