Isoquinolinium salts are well-known N-heterocyclic cationic compounds that have been applied in various research fields, such as materials chemistry and pharmaceutical applications. In particular, isoquinolinium with polyaromatic structures widely investigated due to their intrinsic photophysical properties, including fluorescence emission maxima, lifetime, quantum yield. Notably, fluorescent synthesized via synthetic strategies, alkylation of isoquinoline, oxidation dihydropyridines, rearrangement reactions, transition-metal-catalyzed C-H activation. this review, we summarize the methodologies for diverse applications applications, chemistry, theranostics, DNA binding, sensing, bioimaging.

Rhodium Catalysts Based on Phenyl Substituted Cp Ligands for Indole Synthesis via Oxidative Coupling of Acetanilides and Alkynes

Advanced Synthesis & Catalysis, Journal Year: 2024, Volume and Issue: 366(22), P. 4729 - 4736

Published: Aug. 16, 2024

Abstract Rhodium‐catalyzed oxidative coupling of acetanilides and alkynes via C−H activation is the most powerful synthetic tool for producing indole motif from commercially available precursors. However, this reaction usually requires large catalyst loadings (5 mol% rhodium). In study, a 1,2‐diphenylcyclopentadienyl ligand‐based was developed that works well at 1 loading rhodium. DFT calculations step provided insight into its high catalytic activity. The efficiency also demonstrated in synthesis naturally occurring isocoumarins, such as polygonolide, tubakialactone B penicimarine F. protocols tolerate wide range functional groups, example, halide, nitro, hydroxy, alkoxy.
