We synthesized a series of acridone derivatives for specific binding ligands of i-motifs. Subsequent evaluations showed that B19 could selectively bind to and stabilize the c-myc promoter i-motif without significant binding to the G-quadruplex and duplex

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.
NIS-mediated intramolecular oxidative α-functionalization of tertiary amines: Transition metal-free synthesis of 1,2-dihydro-(4H)-3,1-benzoxazin-4-one derivatives

A novel method for direct α-functionalization of tertiary amines via NIS-mediated oxidative C-O bond formation, where NIS serves as both an oxidant and an iodination reagent, has been developed. The method provides easy access to either iodinated or non-iodinated 1,2-dihydro-(4H)-3,1-benzoxazin-4-ones, depending on the nature of the reactant, via a regioselective transition metal-free approach.
