Category: thiazoleOn March 31, 2022, Zhu, Yu-Shen; Shi, Linlin; Fu, Lianrong; Chen, Xiran; Zhu, Xinju; Hao, Xin-Qi; Song, Mao-Ping published an article in Chinese Chemical Letters. The article was 《Iodine-catalyzed amination of benzothiazoles with KSeCN in water to access primary 2-aminobenzothiazoles》. The article mentions the following:
A facile and sustainable approach for the amination of benzothiazoles I (X = H, N; R = H, 4-Cl, 5-OMe, 6-NO2, 7-C(O)OMe; R1 = H) with KSeCN using iodine as the catalyst in water has been disclosed under transition-metal free conditions. The reaction proceeded smoothly to afford various primary 2-amino benzothiazoles I (R1 = NH2) in up to 96% yield. A series of control experiments were performed, suggesting that a ring-opening mechanism was involved via a radical process. This protocol provides efficient synthesis of primary 2-aminobenzothiazole I (R1 = NH2). After reading the article, we found that the author used 6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Category: thiazole)
6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9) belongs to thiazoles. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities.Category: thiazoleThiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis.
