Abstract
Distinct protocols have been devised for the preparation of hybrid heterocyclic scaffolds like π-extended pyrido-acridines and quinazolino-phenanthridines duly materialized through Rh(III)- and Pd(II)-mediated catalytic courses commencing from acridine and quinazolimine scaffolds. Interestingly, the parent compounds (acridines and quinazolimines) are actualized from 2-aminobenzonitrile and anthranilic acid, where 2-aminobenzonitrile acts as the 1,4-dipolarophilic species and anthranilic acid as the benzyne precursor. The molecular assembly of acridine suggests the participation of two benzyne units. In addition, the structural motif of the quinazolimine ring features one benzyne unit. Further, indolizine ring containing the enaminonitrile skeleton upon exposure to benzyne forms an indolizine fused quinoline ring, decorated with three benzyne units.

Abstract
A visible-light-induced K2S2O8-promoted cascade sulfonation/cyclization reaction was established using 3-(2-(ethynyl)phenyl)quinazolinones as efficient substrates under mild conditions. A series of sulfonated quinolino[2,1-b]quinazolinones were successfully synthesized under transition-metal- and photocatalyst-free conditions. Notably, this strategy has the advantages of room temperature and simple operation, easy scale-up, and good functional group tolerance.

Abstract
Herein, we demonstrate a regioselective intramolecular C-N cross-coupling for the synthesis of 14H-quinazolino[3,2-f]phenanthridin-14-one by using 9-mesityl-10-methylacridinium perchlorate as the visible-light (450-470 nm) photocatalyst. The experiments with BHT, TEMPO, and Stern-Volmer quenching studies helped to rationalize a radical pathway via a SET mechanism.

Abstract
Herein, we report that the dipole moments of tautomers can be the controlling factor for regiodivergent synthesis of either 14H-quinazolino[3,2-f]phenanthridin-14-ones or 6H-quinazolino[1,2-f]phenanthridin-6-ones, selectively, from unmasked 2-([1,1'-biphenyl]-2-yl)quinazolin-4(3H)-one. An intramolecular C(sp2)-NH coupling reaction mediated by PhI(OCOOCF3)2 could lead to two different regioisomers selectively at different temperatures when the dielectric constants of solvents like hexafluoroisopropanol and trifluoroacetic acid matched with the tautomer's dipole moments.

Abstract
Here we report a set of direct functionalization methods of unmasked 2-phenylquinazolin-4(3H)-ones, a privileged alkaloid core, without the installation/removal event of protecting groups or exogenous coordinating moieties. Divergent pathways were modulated with transition-metal catalysts by suppressing competitive reactivities, leading to N-arylation, annulative π-extension, or C-H fluorination.
