Intramolecular Reductive Cyclization of o-Nitroarenes via Biradical Recombination
A visible-light-induced/thiourea-mediated intramolecular cyclization of o-nitroarenes under mild conditions is realized for the first time, which provides an efficient and environmentally friendly way to access pharmaceutical relevant quinazolinone derivatives. The reaction can be easily extended to gram level by using a continuous-flow setup with high efficiency. Mechanistic investigation including control experiments, transient fluorescence, UV-vis spectra, and DFT calculations suggests that the formation of active biradical intermediates via intramolecular single electron transfer (SET) is key stage in the catalytic cycle.

Metal-Free Synthesis of Polycyclic Quinazolinones Enabled by a (NH4)2S2O8-Promoted Intramolecular Oxidative Cyclization
An efficient metal-free, (NH4)2S2O8 mediated intramolecular oxidative cyclization for the construction of polycyclic heterocycles was disclosed. A series of polycyclic quinazolinone derivatives with good functional group tolerance were obtained in high yields. The natural products tryptanthrin and rutaecarpine, as well as their derivatives, were easily synthesized by this strategy. A preliminary mechanism study suggested the carbon-centered radical was involved in the catalytic cycle.

Light-Driven Intramolecular C?N Cross-Coupling via a Long-Lived Photoactive Photoisomer Complex
Reported herein is a visible-light-driven intramolecular C?N cross-coupling reaction under mild reaction conditions (metal- and photocatalyst-free, at room temperature) via a long-lived photoactive photoisomer complex. This strategy was used to rapidly prepare the N-substituted polycyclic quinazolinone derivatives with a broad substrate scope (>50 examples) and further exploited to synthesize the natural products tryptanthrin, rutaecarpine, and their analogues. The success of gram-scale synthesis and solar-driven transformation, as well as promising tumor-suppressing biological activity, proves the potential of this strategy for practical applications. Mechanistic investigations, including control experiments, DFT calculations, UV-vis spectroscopy, EPR, and X-ray single-crystal structure of the key intermediate, provides insight into the mechanism.

Synthesis and evaluation of tetrahydroisoquinoline-benzimidazole hybrids as multifunctional agents for the treatment of Alzheimer's disease
A novel series of tetrahydroisoquinoline-benzimidazole hybrids have been designed and synthesized as multifunctional agents against Alzheimer's disease (AD). These compounds were evaluated for their inhibition of neuroinflammation and human β-secretase (hBACE1), and neuroprotective activity. Among them, compound BD3 possessed significant anti-neuroinflammatory activity (IC50 = 5.07 μM against nitric oxide production) through inhibiting the expression and secretion of proinflammatory cytokines in BV2 cells. Compound BD3 also exhibited moderate hBACE1 inhibitory activity (65.7% inhibition at 20 μM) and potent neuroprotective effect by increasing GSH level and reducing ROS production (91.8% cell viability at 5 μM). Parallel artificial membrane permeation assay demonstrated that BD3 could cross the blood-brain barrier (BBB). Thus, this study demonstrates that the compounds with tetrahydroisoquinoline-benzimidazole scaffold are potential anti-AD agents, and they are worth for the further development.
