A palladium-catalyzed four-component carbonylative cyclization reaction for the synthesis of 2,3-disubstituted quinazolin-4(3H)-ones has been developed. A range of different 2,3-disubstituted quinazolin-4(3H)-one derivatives were prepared in moderate to good yields employing simple and readily accessible 2-iodoanilines, nitro compounds and acid anhydrides as the synthetic precursors. Mo(CO)6 acted...
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.
