Oxidative NHC Catalysis for the Generation of Imidoyl Azoliums: Synthesis of Benzoxazoles was written by Patra, Atanu;James, Anjima;Das, Tamal Kanti;Biju, Akkattu T.. And the article was included in Journal of Organic Chemistry in 2018.Name: 2-(3-Bromophenyl)benzo[d]oxazole This article mentions the following:
N-Heterocyclic carbene (NHC)-catalyzed intramol. cyclization of aldimines generated from 2-amino phenols and aromatic aldehydes leading to the synthesis of 2-arylbenzoxazoles under mild conditions is presented. The reaction proceeds via the generation of the aza-Breslow intermediates from imines and NHC, which under oxidative conditions form the key imidoyl azoliums and a subsequent intramol. cyclization furnishes the product. The reaction tolerates a broad range of functional groups, and the products are formed in generally good yields. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9Name: 2-(3-Bromophenyl)benzo[d]oxazole).
2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives. The benzoxazole moiety is widely found in various natural compounds, which are often found to be biologically active. It is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen and tafamidis.Name: 2-(3-Bromophenyl)benzo[d]oxazole
