Palladium-catalyzed carbonylative synthesis of N-(2-cyanoaryl)benzamides and sequential synthesis of quinazolinones
摘要:
A convenient procedure for the synthesis of N-(2-cyanoaryl)benzamides has been developed. Using aryl bromides and 2-aminobenzonitriles as the substrates, Mo(CO)(6) as the CO source, the desired amides were produced in good yields. Quinazolinones were produced in good yields in a sequential manner as well. (C) 2013 Elsevier Ltd. All rights reserved.
The synthesis of 2,4-disubstituted quinazolines by a palladium-catalyzed reaction of arylboronic acids with N-(2-cyanoaryl)benzamides has been developed with moderate to excellent yields. The method shows good functional group tolerance. In particular, halogen and hydroxyl substituents, which are amenable for further synthetic elaborations, are well tolerated. Moreover, the present synthetic route

The reaction of allylindium reagents and N-(2-cyanoaryl)amides afforded 2-substituted-4-allylquinazolines in good yields via the indium-mediated Barbier-type allylation of nitrile and the following dehydrative cyclization cascade.
