The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Rhodium(II)-Catalyzed [4+3] Cyclization of Triazoles with Indole Derivatives and Its Application in the Total Synthesis of (±)-Aurantioclavine》. Authors are Duan, Shengguo; Xue, Bing; Meng, Hui; Ye, Zihang; Xu, Ze-Feng; Li, Chuan-Ying.The article about the compound:1-Boc-4-Bromoindolecas:676448-17-2,SMILESS:C(C)(C)(C)OC(=O)[N]2C1=CC=CC(=C1C=C2)Br).SDS of cas: 676448-17-2. Through the article, more information about this compound (cas:676448-17-2) is conveyed.
An efficient rhodium(II)-catalyzed [4+3] cyclization reaction of 1-sulfonyl-1,2-3-triazoles and indoles was developed. Azepino[5,4,3- cd]indoles, which are widely distributed in ergot alkaloids with various biol. activities, could be obtained in good to excellent yields. In addition, the total synthesis of (±)-aurantioclavine was completed in four steps from the known compd adopting this [4+3] cyclization as a key step.
When you point to this article, it is believed that you are also very interested in this compound(676448-17-2)SDS of cas: 676448-17-2 and due to space limitations, I can only present the most important information.
