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.

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

The first example of the palladium-catalyzed, three-component tandem reaction of 2-aminobenzonitriles, aldehydes, and arylboronic acids has been developed, providing a new approach for one-pot assembly of diverse quinazolines in moderate to good yields. A noteworthy feature of this method is the tolerance of bromo and iodo groups, which affords versatility for further synthetic manipulations. Preliminary mechanistic experiments indicate that this tandem process involves two possible mechanistic pathways for the formation of quinazolines via catalytic carbopalladation of the cyano group.
