tert‐Butyl hydroperoxide (TBHP) served as the methylsourceunder metal‐free aerobicconditions in the oxidativeamination of a C(sp3)–Hbond to provide quinazolin‐4(3H)‐one and quinazoline derivatives.

A copper-catalysed three-component reaction for constructing a series of quinazoline derivatives has been developed. In this system, solvents act as the reactants and different functional groups are well tolerated to obtain corresponding products in moderate to good yields.

consistent with our computational study on the thermal decomposition of thiourea to form hydrogen sulfide and carbodiimide. This reaction involves a coupling between 2-aminobenzophenone and carbodiimide generated in situ from thiourea to form 4-phenylquinazolin-2(1H)-imine intermediate, and the generation of sulfur-containing reducing agent from hydrogen sulfide and DMSO, which reduces 4-phenylquinazolin-2(1H)-imine

A straightforward single step method for the preparation and/or production of substituted quinazolines is disclosed, wherein said quinazolines preferably contain one substituent at position 4, and may contain other functional groups at various positions, such as 5, 6, 7, and/or 8 of quinazolines. In addition, the extension of this new method leads to the formation of different type of heterocyclic aromatic compounds, that include but are not limited to perimidines, anthrapyrimidin-7-ones (also known as anthrapyrimidinones), anthra[1,9:5, 10]dipyrimidines (also known as quinazoline[5,4-ef]perimidines) and benzo[e]- pyrimido[4,5,6-gh]pyrimidines.
