产品说明
一般描述
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.
