Racemisation-free Esterification of 2-Nitrophenylsulphenyl-protected Amino-acids by Dicyclohexylcarbodi-imide-4-Dimethylaminopyridine

Racemisation during esterification of N-protected amino-acids by dicyclohexylcarbodi-imide-4-dimethylaminopyridine (DDC-DMAP) can be avoided by use of the 2-nitrophenylsulphenyl (Nps) protecting group.
