Copper-catalyzed synthesis of N-aryl acridones from 2-amino benzophenones and aryl boronic acids via sequential double oxidative C–N coupling

, (2019/12/27)
Pot-economic synthesis of N-aryl acridones was performed with 2-aminobenzophenones and aryl boronic acids as starting materials. Cu-catalyzed chelation-assisted oxidative C–N cross-coupling reactions were well merged with the following intra-molecular oxidative dehydrogenative C–H amination reactions under an air atmosphere. The use of reagent capsules can further resolve the compatibility problem of reagents and simplify the operational process, providing a more straightforward access to the target products.

In this paper, we reported the facile synthesis of the π-extended molecules having p-methylenequinone unit from the aromatic ketones, such as fluorenone, xanthone, thioxanthone, dibenzosuberenone, and acridone, in few steps and the results of their physic
Synthesis of Acridones by Palladium-Catalyzed Buchwald-Hartwig Amination

, p. 817 - 820 (2019/04/25)
The Buchwald-Hartwig amination allows an efficient and convenient synthesis of biologically and pharmaceutically important acridones by formation of a six-membered ring. With the described method, a number of derivatives have been synthesized in up to 95% yield by using a variety of anilines as well as benzylic and aliphatic amines.

Hellwinkel, Dieter,Ittemann, Peter
, p. 3165 - 3197 (2007/10/02)
The title compounds 10, 23 are formed in low yields on treatment of 2,2'-organylimino-bisbenzoic acid esters 8 with methyllithium, but in high yields in the intramolecular ester condensation with sodium hydride of triarylamines 12, containing o-acetyl-, a
