TEMPO/PhI(OAc)2-mediated Direct Sulfoximination of Benzoxazoles under Metal-free Conditions was written by Wang, Jian;Tu, Changqing;Feng, Mei-Lin;Li, Nan. And the article was included in Chemistry Letters in 2022.HPLC of Formula: 132227-03-3 This article mentions the following:
A metal-free reaction system consisting of TEMPO and PhI(OAc)2 for the oxidative C-N coupling of benzoxazoles with NH-sulfoximines had been developed to obtain arylsulfoximines I [R1 = H, 5-Cl, 7-Br, etc.; R2 = Me, Et, n-Bu, Bn; R3 = Ph, 4-FC6H4, 2-BrC6H4, etc.]. The reaction could proceed under ambient atm. without any metal catalyst at room temperature to afford the corresponding 2-iminoazoles in moderate to high yields. In the experiment, the researchers used many compounds, for example, 5-Methoxybenzo[d]oxazole (cas: 132227-03-3HPLC of Formula: 132227-03-3).
5-Methoxybenzo[d]oxazole (cas: 132227-03-3) belongs to benzoxazole derivatives. Benzoxazoles belong to the group of well-known antifungal agents with antioxidant, antiallergic, antitumoral and antiparasitic activity. It is found within the chemical structures of pharmaceutical drugs such as flunoxaprofen and tafamidis.HPLC of Formula: 132227-03-3
