Cu-catalyzed β-functionalization of saturated ketones with indoles: a one-step synthesis of C3-substituted indoles was written by Yang, Zhao;Liu, Chengkou;Zeng, Yu;Zhang, Jingming;Wang, Zhixiang;Fang, Zheng;Guo, Kai. And the article was included in RSC Advances in 2016.HPLC of Formula: 4769-96-4 This article mentions the following:
An effective one-pot synthesis of β-indolylketones I [R1 = H, 4-Me, 4-F, etc.; R2 = 2-Me, 5-CN, 6-NO2, etc.] from saturated ketones and indoles was developed. It is noteworthy that this methodol. has a good functional group tolerance (alkyl, nitro, halogen, hydroxyl, methoxyl, carboxyl and ester) and is of great significance to the preparation of many indole heterocycles. In the experiment, the researchers used many compounds, for example, 6-Nitro-1H-indole (cas: 4769-96-4HPLC of Formula: 4769-96-4).
6-Nitro-1H-indole (cas: 4769-96-4) belongs to indole derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.HPLC of Formula: 4769-96-4
