Total Synthesis of (-)-Aspergilazine A was written by Boyd, Emily M.;Sperry, Jonathan. And the article was included in Organic Letters in 2014.Quality Control of (S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid This article mentions the following:

The total synthesis of (-)-aspergilazine A (I), an alkaloid possessing a rare N1′ to C6 bisindole bond, is described. A palladium-catalyzed N-arylation was used to selectively install the N1′-C6 bond in the presence of three other possible arylation sites. The ligand XPhos displayed a unique capability to efficiently carry out the N-arylation while simultaneously suppressing epimerization of the sensitive C9 stereocenters. This total synthesis has confirmed that aspergilazine A is a dimer of brevianamide F. In the experiment, the researchers used many compounds, for example, (S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid (cas: 52448-17-6Quality Control of (S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid).

(S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid (cas: 52448-17-6) belongs to indole derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Quality Control of (S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid

Bromocontryphan: post-translational bromination of tryptophan was written by Jimenez, Elsie C.;Craig, A. Grey;Watkins, Maren;Hillyard, David R.;Gray, William R.;Gulyas, Joseph;Rivier, Jean;Cruz, Lourdes J.;Olivera, Baldomero M.. And the article was included in Biochemistry in 1997.SDS of cas: 52448-17-6 This article mentions the following:

The authors demonstrate that post-translational bromination of a tryptophan residue occurs in the biol. active octapeptide bromocontryphan, purified and characterized from Conus radiatus venom. Clones encoding bromocontryphan were identified from a cDNA library made from C. radiatus venom ducts. The mRNA sequence obtained predicts a prepropeptide which has the mature peptide sequence at the C-terminal end, with the L-6-bromotryptophan residue encoded by UGG, the Trp codon. These data provide the first direct evidence for post-translational bromination of a polypeptide which is translated through the normal cellular machinery. In addition to bromination, the peptide, which induces a “stiff tail” syndrome in mice, has several other modifications, including hydroxylation of Pro³, epimerization of Trp⁴, and C-terminal amidation. Bromocontryphan appears to have the highest d. of post-translational modifications known among gene-encoded polypeptides. The overall result is a mol. which closely resembles marine natural products produced through specialized biosynthetic pathways comprising many enzyme-catalyzed steps.

(S)-2-Amino-3-(6-bromo-1H-indol-3-yl)propanoic acid (cas: 52448-17-6) belongs to indole derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.SDS of cas: 52448-17-6
