DFPE polystyrene

This resin is prepared under conditions optimized to minimize styrene formation during attachment of the linker to the functionalized ethylpolystyrene support. This high substitution, coupled with the lack of amide bonds and potentially acid-sensitive benzylic linkages, makes this support the preferred choice of SPOS of secondary sulfonamides and carboxamides. Applications of FMPE include aminofurazanopyrazines ^[1] and peptide agonists for human orphan receptor BRS-3 ^[2].
