General description
The use of this N-in-Boc protected derivative overcomes most of the problems associated with the preparation of Trp containing-peptides by Fmoc SPPS [1]. Cleavage with TFA generates an N-in-carboxy indole which protects the Trp from alkylation [1,2,3] and sulfonation [1,4,5,6,7]. The N-in-carboxy group is removed under aqueous conditions during normal work-up of the peptide.
