Lavilla, Rodolfo et al. published their research in European Journal of Organic Chemistry in 1999 | CAS: 15366-65-1

5-Iodonicotinic acid (cas: 15366-65-1) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Synthetic Route of C6H4INO2

A unified synthetic strategy for the indolopyridine alkaloid group was written by Lavilla, Rodolfo;Gullon, Francisco;Bosch, Joan. And the article was included in European Journal of Organic Chemistry in 1999.Synthetic Route of C6H4INO2 This article mentions the following:

Thermal or AcCl-induced cyclization of bromo enamide I (R, R1 = H; R2 = Br) 10 affords the pentacyclic derivative I (RR1 = bond, R2 = Br) 12 with high yield and regioselectivity. From this common synthetic intermediate, Pd-catalyzed reactions allow the total synthesis of indolopyridine alkaloids I (RR1 = bond; R2 = CH:CH2, Et, Ac, CHMeOMe). In the experiment, the researchers used many compounds, for example, 5-Iodonicotinic acid (cas: 15366-65-1Synthetic Route of C6H4INO2).
