This paper presents a reevaluation of the synthesis and properties of Fmoc-
His(3-Bum)-OH regarding its application in SPPS with minimal racemization o
f histidine residues during coupling and esterification reactions. By-produ
ct formation during the deprotection of the test peptides could be signific
antly reduced by scavenging the concomitantly formed HCHO, e.g. with methox
yamine. Copyright (C) 2001 European Peptide Society and John Wiley & Sons.
