Zhang, Bo-Sheng; Li, Yuke; Zhang, Zhe; An, Yang; Wen, Yu-Hua; Gou, Xue-Ya; Quan, Si-Qi; Wang, Xin-Gang; Liang, Yong-Min published an article in Journal of the American Chemical Society. The title of the article was 《Synthesis of C4-Aminated Indoles via a Catellani and Retro-Diels-Alder Strategy》.COA of Formula: C12H15N3 The author mentioned the following in the article:
Highly functionalized 4-aminoindoles were synthesized via the three-component cross-coupling of o-iodoaniline, N-benzoyloxyamines, and norbornadiene. The Catellani and retro-Diels-Alder strategy was used in this domino process. o-Iodoaniline, with electron-donating and sterically hindered protecting groups, made the reaction selective toward o-C-H amination. On the basis of d. functional theory calculations, the intramol. Buchwald coupling of this reaction underwent a dearomatization and a 1,3-palladium migration process. The reasons for the control of the chem. selectivity by the protecting groups are given. Moreover, synthetic applications toward 4-piperazinylindole and a GOT1 inhibitor were realized. After reading the article, we found that the author used 4-(Piperazin-1-yl)-1H-indole(cas: 84807-09-0COA of Formula: C12H15N3)
4-(Piperazin-1-yl)-1H-indole(cas: 84807-09-0) belongs to piperazines. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines.COA of Formula: C12H15N3
