Abstract
Here, we explore a dehydrogenative 6π photocyclization method for N-substituted naphthalene carboxamides, which can be conducted in air. This method employs DMSO as both the reaction solvent and oxidant while also stabilizing the excited state of the substrate. Furthermore, the addition of photosensitizer enables the reaction to proceed under a 440-445 nm LED source via energy transfer. The proposed mechanism is initially validated through DFT calculations.

Abstract
Understanding complex reaction systems is critical in chemistry. While synthetic methods for selective formation of products are sought after, oftentimes it is the full reaction signature, i.e., complete profile of products/side-products, that informs mechanistic rationale and accelerates discovery chemistry. Here, we report a methodology using high-throughput experimentation and multivariate data analysis to examine the full signature of one of the most complicated chemical reactions catalyzed by palladium known in the chemical literature. A model Pd-catalyzed reaction was selected involving functionalization of 2-bromo-N-phenylbenzamide and multiple bond activation pathways. Principal component analysis, correspondence analysis and heatmaps with hierarchical clustering reveal the factors contributing to the variance in product distributions and show associations between solvents and reaction products. Using robust data from experiments performed with eight solvents, for four different reaction times at five different temperatures, we correlate side-products to a major dominant N-phenyl phenanthridinone product, and many other side products.

Abstract
To address the growing health threat posed by drug-resistant pathogenic microorganisms, the development of novel antimicrobial medications with multiple mechanisms of action is in urgent demand. With traditional antibacterial drug resources challenging to push forward, developing new antibacterial drugs has become a hot spot in biomedical research. In this study, we tested the antibacterial activity of 119 phenanthridine derivatives via the antibacterial assay and obtained 5 candidates. The cytotoxicity assay showed one phenanthridine derivative, HCK20, was safe for mammalian cells below 125 µM. HCK20 was verified to possess significant antibacterial activity to Streptococcus spp., such as Streptococcus pneumoniae, Streptococcus agalactiae, Streptococcus suis, Streptococcus dysgalactiae, and Streptococcus equi with MICs ranging from 15 to 60 µM. Furthermore, we found that HCK20 probably achieved its bacterial inhibition by influencing the permeability of bacterial cell walls via interacting with Streptococcal penicillin-binding proteins (PBPs). Our results suggest that this phenanthridine derivative, HCK20, has great potential to become a novel antibacterial agent that can be a potent treatment for streptococcal infections.

DMF as CO Surrogate in Carbonylation Reactions: Principles and Application to the Synthesis of Heterocycles. Catalysts 2021.

Abstract
Transition metal-catalyzed carbonylation reactions have emerged as one of the most relevant synthetic approaches for the preparation of carbonyl-containing molecules. The most commonly used protocol for the insertion of a carbonyl moiety is the use of carbon monoxide (CO) but, due to its toxic and explosive nature, this process is not suitable at an industrial scale. More recently, the chemistry of CO surrogates has received large attention as a way to use less expensive and more environmentally friendly methods. Among the various CO surrogates, N,N-dimethylformamide (DMF) has been paid greater attention due to its low cost and easy availability. This mini-review gives appealing insights into the application of DMF as a CO surrogate in metal-catalyzed carbonylations; in particular, in the first part we will give a general state of the art of these reactions for the preparation of carbonyl-containing molecules; then, we will take into account all the various synthetic approaches for the metal-catalyzed carbonylative synthesis of heterocycles using DMF as a CO surrogate. Each protocol has been discussed critically in order to screen the best synthetic method and to offer perspective on trends and future directions in this field.

Abstract
Phenanthridinones are important heterocyclic frameworks present in a variety of complex natural products, pharmaceuticals and displaying wide range of pharmacological actions. Its structural importance has evoked a great deal of interest in the domains of organic synthesis and medicinal chemistry to develop new synthetic methodologies, as well as novel compounds of pharmaceutical interest. This review focuses on the synthesis of phenanthridinone scaffolds by employing aryl-aryl, N-aryl, and biaryl coupling reactions, decarboxylative amidations, and photocatalyzed reactions.

A metal-free aromative cascade has been developed for the synthesis of diverse heterocycles from readily accessible hydroxy/aminochalcones and acid/alkyl halides. The cascade being by a base-mediated intramolecular aldol cyclization/dehydration sequence to provide a triene, which sets the stage for a 6π-electrocyclization/oxidative aromatization to access diverse heterocyclic scaffolds.

Abstract
A palladium catalyzed synthesis of N–H phenanthridinones was developed via C–H arylation. The protocol gives phenanthridinones regioselectively by one-pot reaction without deprotection. It exhibits broad substrate scope and affords targets in up to 95% yields. Importantly, it could be applied for the less reactive o-chlorobenzamides. Pd(t-Bu3P)2/KOAc proved to be a good combination for one-pot synthesis of N–H phenanthridinones with up to 95% yield.![]()

Abstract
A novel Pd-catalyzed intermolecular dehydrogenative annulation of aryl iodides and aryl carbamic chlorides for the efficient synthesis of phenanthridinone derivatives was developed. Simple aryl iodides and carbamic chlorides readily made from various anilines, a broad substrate scope with hetero/polycycles, as well as high-value products, make this direct dehydrogenative annulation approach very practical and attractive.

Bioorg Med Chem 2014; 22:2799-808.

Abstract
Retinoic acid receptor-related orphan receptors (RORs), which belong to the nuclear receptor superfamily, regulate many physiological processes, including hepatic gluconeogenesis, lipid metabolism, immune function and circadian rhythm. Since RORs resemble liver X receptors (LXRs) in the fold structure of their ligand-binding domains, we speculated that ROR-mediated transcription might be modulated by LXR ligands, in line with the multi-template hypothesis. Therefore, we screened our LXR ligand library for compounds with ROR ligand activity and identified a novel ROR ligand with a phenanthridin-6(5H)-one skeleton. Structure-activity relationship studies aimed at separating ROR inverse agonistic activity from LXR-agonistic activity enabled us to develop a series of ROR inverse agonists based on the phenanthridin-6(5H)-one skeleton, including a RORγ-selective inverse agonist.

Abstract
The palladium-catalyzed annulation of arynes by substituted o-halobenzamides produces N-substituted phenanthridinones in good yields. This methodology provides this important heterocyclic ring system in a single step by simultaneous C-C and C-N bond formation, under relatively mild reaction conditions, and tolerates a variety of functional groups.

Abstract
We identified a fused heteroaromatic amido structure based on the phenanthridine skeleton as a superior scaffold for candidate drugs with potent anti-HCV activity. Among the compounds synthesized, a phenanthridine analogue with a 1,3-dioxolyl group (24) possessed the most potent anti-HCV activity (EC(50) value: 50 nM), with acceptable cytotoxicity. The structural development and structure-activity relationships of these compounds are described.
