Access to 3-alkylselenindoles by multicomponent reaction of indoles, selenium powder and unactivated alkyl halides under transition-metal-free conditions was written by Liu, Huan;Cai, Zhong-Jian;Ji, Shun-Jun. And the article was included in Chinese Chemical Letters in 2022.Formula: C8H6N2O2 This article mentions the following:
Herein, a convenient and efficient multicomponent reaction of indoles, selenium powder and unactivated alkyl halides is reported. This protocol provides a practical, and facile approach for the synthesis of 3-alkylselenindole derivatives The advantages of this strategy include mild and transition-metal-free conditions, broad functional group tolerance, the use of simple and easily accessible selenium powder and alkyl halides as coupling partners. More importantly, the reaction proceeded smoothly with a large scale (> 10 g, > 90% yield), which further highlighted the potential application of this selenation strategy. In the experiment, the researchers used many compounds, for example, 6-Nitro-1H-indole (cas: 4769-96-4Formula: C8H6N2O2).
6-Nitro-1H-indole (cas: 4769-96-4) belongs to indole derivatives. Indole is an important structural motif of various drugs, therapeutic leads besides its prevalence in numerous natural products, agrochemicals, perfumery, and dyes. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Formula: C8H6N2O2
