Description

General description

Fmoc-Cys(Thp)-OH is a new building block for Fmoc SPPS, in which the sulfhydryl group is protected with the acid-cleavable tetrahydropyranyl (Thp) group ^[1]. The use of Fmoc-Cys(Thp)-OH has been shown to give superior results to the corresponding S-Trt, S-Dpm, S-Acm, and S-StBu derivatives.
