Methyl N-(substituted benzoyl)anthranilates were found to possess inhibitory activity against the powdery mildew of cucumber caused by Sphaerotheca fuliginea. Both the anthranilate and the N-benzoyl moieties were essential for this type of fungicidal activity. Substitution at the 2- and 4-positions of the N-benzoyl group was unfavorable to the activity except for the 4-methoxy group. Substitution at the 3-position varied the fungicidal activity to various extents. The variation in the activity of 3-substituted derivatives was analyzed quantitatively with substituent parameters and regression analysis indicating that the variation in the steric dimension of substituents was most responsible for the activity.

copper‐catalyzed domino method for synthesis of isoquinolino[2,3‐a]quinazolinones has been developed using readily available, substituted methyl 2‐(2‐haloobenzamido)benzoates and nitriles as the starting materials. The domino process comprises an Ullmann‐type C‐arylation, intramolecular addition of NH with CN, and nucleophilic attack of amino to ester group. The inexpensive, convenient and efficient copper‐catalyzed

A photocatalytic, XAT mediated Smiles-Truce biaryl synthesis is described. The reaction uses mild methods to generate and chemoselectively harness capricious aryl radicals, efficiently furnishing valuable biaryl products. The reaction utilises a simple yet underexplored amide linker, which enables a challenging formal C−N arylation of anilines.

Cul/4-hydroxy-L-proline catalyzed coupling of N-substituted o-bromobenzamides with formamide takes place at 80 degrees C, affording 3-substituted quinazolinones directly. Under these conditions other amides that were tested only provided simple coupling products, which can be converted into 2,3-disubstituted quinazolinones via HMDS/ZnCl2 mediated condensative cyclization.
