  A four-component procedure for the preparation of substituted quinazolines from anilines, aromatic aldehydes and ammonium iodide is described. The C–H bond ortho to the amino group in anilines was directly functionalized under metal-free conditions. Two aldehydes were involved in this reaction and ammonium iodide was used as one of the nitrogen sources. This reaction provides a strategy for the facile

  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

  An I2/KI-promoted oxidative C–C bond formation reaction from C(sp3)–H and C(sp2)–H bonds has been used to construct quinazoline skeletons from N,N′-disubstituted amidines. The required substrates are readily prepared from the corresponding acyl chlorides, anilines, and alkyl/benzylamines by sequential amidation, chlorination, and amination reactions. Under the optimal oxidative cyclization conditions
