Abstract
We investigated the effects of bases, resins, and S-protecting groups on the extent of racemization at the C-terminal cysteine during Fmoc-b ased(Fmoc=fluoren-9-yl-methoxy-carbonyl) solid phase peptide synthesis . The use of 2-chlorotrityl resin was most effective in suppressing th e racemization caused by the base treatment for Fmoc-cleavage. Somatos tatin was successfully synthesized with practically no racemization us ing 2-chlorotrityl resin by Fmoc-chemistry.
