Various 2-phenylquinazoline derivatives were synthesized under metal-free conditions from readily available 2-aminophenyl ketones and benzylamines via condensation and oxidative cyclization using 2,3-dichloro-5,6-dicyano-1,4- benzoquinone (DDQ) as a versatile reagent. The reaction gave the corresponding 2-phenylquinazoline derivatives in good to excellent yields (up to 92%). Georg Thieme Verlag Stuttgart ? New York.

The analogous three-component synthesis strategy for substituted 1,2,4-oxadiazole and quinazoline derivatives from readily available benzaldehyde, benzylamine and hydroxylamine or aniline has been developed. Both the cascade reaction sequences involves nucleophilic addition of C?N bond, introduction a halogen donor, nucleophilic substitution and Cu(II)-catalyzed aerobic oxidation. This synthesis methodology demonstrated good yields, broad substrate scope and oxygen as a green oxidant. Thus, this synthesis protocol provides strategies for the construction of substituted 1,2,4-oxadiazole and quinazolines from readily and simple starting materials. (Figure presented.).

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, ha
