CuII/H-USY as a regenerable bifunctional catalyst for the additive-free C-H amination of azoles was written by Henrion, Mickael;Smolders, Simon;De Vos, Dirk E.. And the article was included in Catalysis Science & Technology in 2020.Application In Synthesis of 5-Methoxybenzo[d]oxazole This article mentions the following:
A copper-exchanged H-USY zeolite catalyst was developed for the direct C-H amination of azoles with secondary amines in HFIP. The reaction was performed under air without any external additive. The Cu/H-USY catalyst could be regenerated for further re-use without significant decrease in activity. In the experiment, the researchers used many compounds, for example, 5-Methoxybenzo[d]oxazole (cas: 132227-03-3Application In Synthesis of 5-Methoxybenzo[d]oxazole).
5-Methoxybenzo[d]oxazole (cas: 132227-03-3) belongs to benzoxazole derivatives. Benzoxazole derivatives have gained a lot of importance in the past few years because of their use in intermediates for the preparation of new biological materials. A number of marketed drugs are available having benzoxazole as core active moiety like, nonsteroidal anti-inflammatory drug (NSAID)—flunoxaprofen, benoxaprofen, antibiotic—calcimycin.Application In Synthesis of 5-Methoxybenzo[d]oxazole
