Exploring an anomaly: the synthesis of 7,7′-diazaindirubin through a 7-azaindoxyl intermediate was written by Shriver, James A.;Wang, Katelyn R.;Patterson, Andrew C.;DeYoung, James R.;Lipsius, Richard J.. And the article was included in RSC Advances in 2020.Category: indole-building-block This article mentions the following:
Two independent methods generating 7-azaindoxyl as an intermediate verified that 7,7′-diazaindirubin was formed exclusively over 7,7′-diazaindigo. This contrasted with long-standing knowledge related to the reactivity of indoxyl, which proceeded via a radical-initiated homodimerization process, leading to indigo. A series of experiments confirmed 7-azaindoxyl as an intermediate with resulted suggesting a condensation pathway followed by oxidation In the experiment, the researchers used many compounds, for example, 6-Nitro-1H-indole (cas: 4769-96-4Category: indole-building-block).
6-Nitro-1H-indole (cas: 4769-96-4) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Category: indole-building-block
