Iodine/Palladium Approaches to the Synthesis of Polyheterocyclic Compounds [PDF]

open access: yesThe Journal of Organic Chemistry, 2010
A simple, straightforward strategy for the synthesis of polyheterocyclic compounds (PHCs) is reported, which involves iterative cycles of palladium-catalyzed Sonogashira coupling, followed by iodocyclization using I(2) or ICl. A variety of heterocyclic units, including benzofurans, benzothiophenes, indoles, and isocoumarins, can be efficiently ...

Synthesis of New 5-Aryl-benzo[f][1,7]naphthyridines via a Cascade Process (Ugi-3CR/Intramolecular Aza-Diels-Alder Cycloaddition)/Aromatization

open access: yesMolecules, 2018
A series of eight new 5-aryl-benzo[f][1,7]naphthyridines were synthesized in 17 to 64% overall yields via an improved MW-assisted cascade-like one pot process (Ugi–three component reaction/intramolecular aza-Diels-Alder cycloaddition) coupled to an

Broad‐Spectrum Antiviral Agents against SARS‐CoV‐2 Variants Inhibit the Conserved Viral Protein Nsp1–RNA Interaction

open access: yesAngewandte Chemie, Volume 136, Issue 47, November 18, 2024.
The demand for robust antiviral approaches is underscored by the continued COVID‐19 spread. SARS‐CoV‐2 Nsp1, highly conserved among SARS‐CoV‐2 variants, plays a pivotal role in controlling host protein expression and viral RNA translation. A small‐molecule Nsp1 inhibitor exhibited antiviral activity against various sarbecoviruses, signifying a ...

One‐Pot Three‐Component Coupling Access to Indolizine‐Pyrrolodiazepine Hybrid Structures

open access: yesAsian Journal of Organic Chemistry, Volume 14, Issue 6, June 2025.
One‐pot three‐component coupling of pyridine‐2‐acetonitrile, N‐substituted pyrrole‐2‐carboxaldehyde, and TMSCN in the presence of DBU allowed facile access to a novel indolizine‐pyrrolodiazepine hybrid structure via a domino aldol condensation‐Michael addition‐cycloisomerization‐imine formation process enabling sequential construction of two ...
