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

Visible‐light‐induced synthesis of substituted quinazolines using1‐(2‐aminoaryl)ethan‐1‐ones in conjunction with arylmethanamines as starting materials.
A copper-catalyzed process for the synthesis of substituted quinazolinesfrom benzonitriles and 2-ethynylanilines using molecular oxygen (O2) as sole oxidant is described. The mild catalytic system enabled the effective cleavage of the C–C triple bond and construction of new C–N and C–C bonds in one operation. Furthermore, the compound N,N-dimethyl-4-(2-(4-(trifluoromethyl)phenyl)quinazolin-4-yl)aniline
