Convenient domino protocol was developed for the synthesis of 2-arylquinazolin-4-amines by the reaction of N-(2-cyanophenyl) substituted benzimidoyl isothiocyanates with isopropyl amine. The major advantages of this protocol are short reaction times, mild conditions, simple work up, high yields, and pure products. The efficacy of this protocol owes to the competence of synthesis, pure isolation of

the synthesis of secondary amine N-(2-(substitutedphenyl)quinazolin-4(3H)-ylidene) carbothioamides and O-alkyl N-2-(substitutedphenyl)quinazolin-4(3H)-ylidene carbamothioates has been described. It involves the cascade reaction of various secondary amines or alcohols with imidoylisothiocyanates in acetonitrile to afford the desired compounds in excellent yields. The reaction time was 48 h under reflux

A simple convenient protocol for the synthesis of methyl2-[3-(2-(substituted phenyl)quinazolin-4-yl)thioureido] alkanoates is described. It involves the domino reaction of various amino acid esters with imidoylisothiocyanates in ethyl acetate to afford quinazoline thiourea derivatives in excellent yields. Short reaction time, mild condition, simple work up, high yields, and pure products are the major
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
