Herein, an iridium(iii)-catalysed electrooxidative intramolecular dehydrogenative C-H/N-H coupling of unprotected 2-alkenyl anilines is described. The developed method allows the synthesis of a variety of 3-substituted N-H indole scaffolds under undivided electrolytic conditions. Mechanistic studies suggest that the reaction proceeds through the electro-oxidation induced reductive elimination pathway.

A readily accessible and bench-stable water-soluble hypervalent iodine(III) reagent (phenyliodonio)sulfamate (PISA) with an I-N bond was synthesized, and its structure was characterized by X-ray crystallography. With PISA, various indoles were synthesized via C-H amination of 2-alkenylanilines involving an aryl migration/intramolecular cyclization cascade with excellent regioselectivity in aqueous CH3CN. Notably, using this new method as the key step, not only two drug molecules, indometacin and zidometacin, but also another bioactive molecule, pravadoline, were synthesized.

Addition of nitroalkanes toortho-halonitrobenzenes: A new synthesis of 4-chloro-7-(trifluoromethyl)quinoline

Base-mediated reaction of ortho-nitroaryl chlorides and fluorides with nitroalkanes followed by an oxidative Nef reaction provides aryl ketones. With this simple procedure, methylketone 6 was prepared in 91% yield. 6 was then converted in three steps (60-65% yield) to 4-chloro-7-(trifluoromethyl)quinoline (2), an intermediate in the synthesis of the antihypertensive agent losulazine (U-54,669, 1).
