An improved and practical synthesis of Fmoc Rink linker
摘要:
Fmoc Rink linker is a widely used peptide-resin linker in the solid-phase synthesis of peptide-amides. This paper describes an improved and practical eight-step synthetic approach for this compound in a 50% overall yield, using p-hydroxybenzaldehyde as the starting material. The procedure is operationally simple and amenable to scale-up synthesis.
