description
Tetrahydropyranyl (Thp), a new S,O-acetal nonaromatic protecting group for cysteine, which has been shown to be superior to Trt, Dpm, Acm, and StBu in solid-phase peptide synthesis using the Fmoc/tBu strategy. Cys racemization and C-terminal 3-(1-piperidinyl)-alanine formation were minimized when the Cys was protected with Thp accompanied by improved solubility of Cys-containing protected peptides. Complete deprotection can be carried out with either TFA/TIS/DCM (10:1.5:88.5) within 5 min or with HCl/dioxane (12:88)in 2h.
