FMoc-N-Me-Cys(Trt)-OH Chemical Properties,Usage,Production

Uses

Fmoc-N-Me-L-Cys(Trt)-OH (CAS# 944797-51-7) is an fmoc- and trityl-protected derivative of L-cysteine (C995000) used as a building block for peptides or peptide fragments, such as the solid-phase synthesis of Triostin A.

Uses

Fmoc-N-Me-Cys(Trt)-OH is a Fmoc-protected derivative of N-methyl cysteine used as a building block to prepare peptide thioesters under acidic conditions. The residue attached to the amino group of N-methylcysteine can migrate to the cysteinyl thiol group, resulting in the formation of a peptide thioester. The introduction of this Fmoc-protected derivative is best achieved using HATU as a coupling reagent in the presence of DIPEA (N, N-Diisopropylethylamine).
It can also be used to prepare Fmoc-N-Me-Cys(Trt)-OAllyl intermediate for the solid-phase synthesis of dithiol Triostin A.
