Abstract

A novel method for Fmoc/tBu solution-phase peptide synthesis and the development of a new benzyl-type group-assisted purification (GAP) protecting group is reported. This GAP protecting group is utilized in place of a polymer support, facilitating C→N Fmoc peptide synthesis without chromatography or recrystallization. The GAP group can be added and removed in high yield, and was used to synthesize over 1 gram of the immunostimulant, thymopentin, in high overall yield (83 %) and purity (99 %). Fmoc/tBu solution-phase peptide synthesis and the development of a new benzyl-type group-assisted purification (GAP) protecting group is reported. This new GAP protecting group replaces a polymer support, facilitating C→N Fmoc peptide synthesis without chromatography or recrystallization. Over 1 gram of the immunostimulant, thymopentin, was synthesized in high overall yield (83 %) and purity (99 %).
