  A novel and convenient procedure for the synthesis of quinazolinones has been developed. Using 2-bromoformanilides and organo nitros as substrates and Mo(CO)6 as a multiple promoter, the desired products were isolated in moderate to excellent yields in the presence of a palladium catalyst. Here, Mo(CO)6 was not only a CO source, but also a nitro compound reducing reagent and a cyclization promoter

  已经开发了新颖且方便的合成喹唑啉酮的方法。使用2-溴甲酰苯胺和有机亚硝基作为底物，使用Mo（CO）6作为多重促进剂，在钯催化剂存在下，以中等至极好的收率分离出所需的产物。在此，Mo（CO）6不仅是CO源，而且是硝基化合物还原剂和环化促进剂。

  synthesis of quinazolin-4(3H)-ones via the reaction of quinazoline-3-oxides with primary amines is described. This approach is demonstrated to be applicable for a broad range of substrates and proceeds efficiently under metal-free and mild reaction conditions employing easily available tert-butyl hydroperoxide as the oxidant. Remarkably, 3-(2-(1H-indol-3-yl) ethyl)quinazolin-4(3H)-one 3w, which was conveniently

  Cul/4-hydroxy-L-proline catalyzed coupling of N-substituted o-bromobenzamides with formamide takes place at 80 degrees C, affording 3-substituted quinazolinones directly. Under these conditions other amides that were tested only provided simple coupling products, which can be converted into 2,3-disubstituted quinazolinones via HMDS/ZnCl2 mediated condensative cyclization.

  A selective functionalization of C–C═C bonds toward N–C═O bonds is realized by an n-Bu4NI-catalyzed reaction of 3-methylindoles with primary amines using TBHP as the unique oxidant. The systematic process involves oxygenation, nitrogenation, ring-opening, and recyclization, affording a broad range of quinazolinones in good to excellent yields.
