Tryptophan chemistry
WebPeptide ligation–desulfurization chemistry at 2-thiol tryptophan (Trp) is described for the first time. Installation of a thiol auxiliary was achieved through late-stage chemoselective sulfenylation chemistry at the 2-position of the indole ring of Trp either in solution or on solid support, thus abrogating the need for the preparation of a pre-formed thiolated amino acid. WebNov 20, 2024 · Tryptophan (Trp) holds a unique place in biology for a multitude of reasons. It is the largest of all twenty amino acids in the translational toolbox. Its side chain is indole, …
