Abstract
We report an efficient iron-catalyzed cross-dehydrogenative coupling [4 + 2] annulation of secondary/tertiary anilines with quinazolinones to generate quinoline-spiroquinzolinones. The reaction proceeds smoothly with a relatively broad variety of functional groups, a cheap transition metal catalyst (FeCl3), and environmentally friendly oxidant (H2O2/O2) under mild reaction conditions. Creatively, N-methylanilines are employed for the first time for the cycloaddition as both methyl and methylene sources attached to the N atom of tetrahydroquinolines.

Abstract
For the first time, the sequential reaction of peroxyoxindole that involves base-promoted oxidative fragmentation to isocyanate formation and primary amine or amino alcohol accelerated skeletal rearrangement to synthesize exo-olefinic-substituted quinazolinone or oxazoloquinazolinone is reported. The advantages of this new reaction include a broad substrate scope and transition-metal-free and room-temperature conditions. The formation of the isocyanate as a key intermediate that accelerates oxidative skeletal rearrangement has been confirmed by trapping experiments and spectroscopic evidence.

Abstract
A novel procedure for a one-pot cascade reaction of o-aminoacetophenones and aryl/aliphatic isocyanates catalyzed/oxidized by the [Pd]/[Ag] system was developed. The reaction involves two C-N bond and one C-C bond formations during the double annulation process and the desired indoloquinazolinones and derivatives were afforded up to 81% yields from readily available substrates with a tolerance of a broad variety.

Abstract
Herein, we report an eco-friendly synthesis of a new series of quinazolinone-based derivatives as potential PARP-1 inhibitors. The 4-quinazolinone scaffold was utilized as a bioisostere to the phthalazinone core of the reference compound Olaparib. Most of the synthesized compounds displayed appreciable inhibitory activity against PARP-1. Compound 12c showed inhibitory activity at IC50 = 30.38 nM comparable to Olaparib, which has IC50 = 27.89 nM. Cell cycle analysis was performed for compounds 12a and 12c, and both exhibited cell growth arrest at G2/M phase in the MCF-7 cell line. In addition, both compounds increased the programmed apoptosis compared to the control. Furthermore, molecular docking of the final compounds into the PARP-1 active site was executed to explore their probable binding modes. Also, a computational QSAR and in silico ADMET study was performed. The results of this study revealed that some of the newly synthesized compounds could serve as a new framework to discover new PARP-1 inhibitors with anti-cancer activity.
