Abstract
An efficient and simple copper catalytic system has been developed for the synthesis of medicinally important 2-substituted quinazoline-4(3H)-ones from 2-aminobenzonitrile and benzyl alcohol derivatives and additionally 2-substituted quinazolines from 2-aminobenzylamine and benzaldehyde derivatives. Mild oxidant H2O2 was utilized, providing excellent product yields. The molecular structure of one of the compounds was substantiated through SC-XRD. The versatility of the protocol was demonstrated through gram-scale syntheses.

Abstract
This is the first report on a facile tandem route for synthesizing quinazolinones at room temperature from various aminobenzamides and in situ-generated aldehydes. The latter was formed via C[double bond, length as m-dash]C bond cleavage, and the overall reaction proceeded using molecular oxygen as a clean oxidant in the absence of a photocatalyst. Visible light, which was indispensable for the entire course of the reaction, played multiple roles. It initially cleaved styrene to an aldehyde, then facilitated its cyclization with an o-substituted aniline, and finally promoted the dehydrogenation of the cyclized intermediate. The previous step provided the feedstock for the next step in the reaction, thereby preventing volatilization, oxidation, and polymerization of the aldehyde. Thus, the overall process is simple, environmentally benign, and economically feasible.

Abstract
An efficient and general carbonylative procedure for the synthesis of 3,4-dihydroquinazolin-2(1H)-one from 1-(halomethyl)-2-nitrobenzenes and aryl/alkyl amines have been explored. In this approach, to avoid of using toxic CO gas, a solid and stable CO precursor, TFBen (benzene-1,3,5-triyl triformate), was utilized. With elemental selenium as the catalyst, a variety of aryl/alkyl amines has been tolerated well to afford the corresponding 3,4-dihydroquinazolin-2(1H)-one products in moderate to excellent yields under mild reaction condition.

Abstract
A mild and atom-economic method was developed for direct and efficient synthesis of quinazolinones through a transition-metal-free aerobic oxidative cascade annulation reaction of widely available o-aminoarylnitriles and alcohols. Air could be employed as an effective oxidant under mild conditions, generating water as the only byproduct. Possibly owing to the "cesium effect", the water-soluble base CsOH was found to be crucial in all key steps of the reaction mechanism. Because a wide range of substrates can be used to prepare substituted quinazolinones without contamination by transition-metal residues, this method may be of interest for application in pharmaceutical synthesis. Possible reaction paths were also proposed according to control reactions.

Abstract
A transition-metal-free procedure for the synthesis of a highly valuable class of heteroaromatics, quinazolines, was developed by using easily available 2-aminobenzylamines and α,α,α-trihalotoluenes. The transformation proceeded smoothly in the presence of only sodium hydroxide and molecular oxygen in water at 100 °C, furnishing a variety of 2-aryl quinazolines. The crystallization process of the crude reaction mixture for the purification of the solid products circumvents huge solvent-consuming workup and column chromatographic techniques, which make the overall process more sustainable and economical.

Abstract
Abstract
Receptor tyrosine kinases (RTKs), such as epidermal growth factor receptor (EGFR), are involved in multiple human tumors. Therefore, RTKs are attractive targets for various antitumor strategies. Two classes of tyrosine kinase antagonists were applied in the clinic for monoclonal antibodies and small-molecule tyrosine kinase inhibitors. A well-studied class of small-molecule inhibitors is represented by 4-anilinoquinazolines, exemplified by gefitinib and erlotinib as mono-targeted EGFR inhibitors, which were approved for the treatment of non-small-cell lung cancer. Mono-target drugs may result in drug resistance and the innovation of multi-target drugs has grown up to be an active field. Recent advances in research on antitumor bioactivity of 4-anilino(or phenoxy)quinazoline derivatives with multiple targets are reviewed in this paper. At the same time, synthetic methods of quinazolines were introduced from the point of building the ring skeleton and based on the types of reaction.
