, p. 1495 - 1503 (2020)
A new and practical method has been developed for the synthesis of 2,4-disubstituted quinolines via one-pot three-component reaction of o-amino arylketones, aldehydes and ammonium acetate in high yields by using DDQ in CH3CN under mild conditio
TMSOTf-catalyzed synthesis of substituted quinazolines using hexamethyldisilazane as a nitrogen source under neat and microwave irradiation conditions

In this article, we report an efficient and mild synthetic route for the construction of substituted quinazolines from functionalized 2-aminobenzophenones with various benzaldehydes usingcat. TMSOTf and hexamethyldisilazane (HMDS) under neat, metal-free and microwave irradiation conditions in which gaseous ammonia was formedin situ. This synthetic protocol provided the desired quinazolines with a broad substrate scope in good to excellent yields. Some structures were confirmed by X-ray single-crystal diffraction analysis.
Four-component quinazoline synthesis from simple anilines, aromatic aldehydes and ammonium iodide under metal-free conditions

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 a
