The use of anhydrous CeCl3 as a catalyst for the synthesis of 3-sulfenyl indoles was written by Silveira, Claudio C.;Mendes, Samuel R.;Wolf, Lucas;Martins, Guilherme M.. And the article was included in Tetrahedron Letters in 2010.Formula: C14H9NO2S This article mentions the following:
Anhydrous CeCl3 was successfully used as a catalyst for the synthesis of several 3-sulfenyl indoles in good to excellent yields through the reaction of indoles with N-(alkylthio) and N-(arylthio)phthalimides in DMF. In the experiment, the researchers used many compounds, for example, 2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4Formula: C14H9NO2S).
2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.Formula: C14H9NO2S
