Molecular oxygen-mediated radical alkylation of C(sp3)-H bonds with boronic acids was written by Yang, Le;Qiu, Zhihong;Wu, Jintao;Zhao, Jianyou;Shen, Tong;Huang, Xuan;Liu, Zhong-Quan. And the article was included in Organic Letters in 2021.Name: 2-Quinoxalinol This article mentions the following:
A direct and site-specific alkylation of (sp3)C-H bond with aliphatic boronic acid was achieved. By simply heating glycinate and amines together with alkylboronic acids under an oxygen atm., a variety of unnatural α-amino acids and peptides could be obtained in good yields. In the experiment, the researchers used many compounds, for example, 2-Quinoxalinol (cas: 1196-57-2Name: 2-Quinoxalinol).
2-Quinoxalinol (cas: 1196-57-2) belongs to quinoxaline derivatives. Condensed heterocycles of quinoxalines have become attractive targets in synthetic and medicinal chemistry due to their significant biological activities. Quinoxaline-1,4-di-N-oxide derivatives have shown to improve the biological results and are endowed with anti-viral, anti-cancer, anti-bacterial, and anti-protozoal activities with application in many other therapeutic areas.Name: 2-Quinoxalinol
