Abstract
Herein, we report a novel, rapid and efficient route to the spiroquinazolinone framework via an umpolung strategy mediated by molecular iodine. A library of functionalized spiroquinazolinone iodide salts was synthesized in moderate to good yields under ambient, metal-free and mild conditions. The current methodology opens up a new efficient and concise strategy for the construction of spiroquinazolinones.

Abstract
The multicomponent-multicatalyst reaction ((MC)2R) and visible-light catalysis have emerged as green and powerful strategies for achieving ideal syntheses. Here, we report the first example of a visible-light-induced approach toward spiroquinazolin(thi)ones. This (MC)2R features an eco-friendly energy source and solvent, metal-free catalysts, step- and atom-economy, a relay catalysis strategy, air as green oxidant, mild conditions, and easily accessible starting materials.

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.

Synthesis of Substituted Cinnamido Linked Quinazolinone Congeners as Potential Anticancer Agents via Mitochondrial Dependent Intrinsic Apoptotic Pathway. Anticancer Agents Med Chem 2019; 19:1935-1948. [PMID: 31490766 DOI: 10.2174/1871520619666190906162537] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/30/2019] [Accepted: 07/19/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND The synthesis of novel heterocyclic scaffolds with amide functionality is a key research area due to their plethora of medicinal applications. The present study aims to explore the synthesis of new cinnamido linked quinazolinone congeners and their potential as anticancer agents. METHODS Cytotoxicity evaluation, Cell cycle analysis, JC-1 staining, ROS, Annexin V assays, AO/EB, DAPI nuclear staining, Colony-forming assay and Western blot analysis. RESULTS Among the synthesized compounds, 5eb and 5fc have shown promising cytotoxic activity with an IC50 value of 3.89±1.01µM and 4.05±0.62µM against HeLa cell lines. The flow-cytometry analysis demonstrated that the compound 5eb arrested the sub-G1 phase of the cell cycle and induced apoptosis. Furthermore, the compound 5eb triggered the collapse of mitochondrial membrane potential (ΔΨm), which was assessed by JC-1 staining and also induced the generation of Reactive Oxygen Species. An increase in the expression of proapoptotic proteins such as Bax, p53, cleaved PARP and cleaved caspase-3 by 5eb confirmed the activation of the mitochondrial-dependent intrinsic apoptosis pathway. CONCLUSION Our results suggest that compound 5eb and 5fc of cinnamido linked quinazolinone derivatives could serve as potential leads in the development of novel chemotherapeutic agents.
