Journal of Heterocyclic Chemistry, Volume 63, Issue 6, Page 982-996, June 2026.Quasi T‐shaped three‐way benzo[b]thiophene scaffolds, containing iodine atom(s) at the 4‐ and/or 7‐position, were prepared by several methods such as silica gel‐assisted cyclization. The iodobenzo[b]thiophenes thus prepared were subjected to Sonogashira cross couplings to give various ethynylbenzo[b]thiophenes.

C4 Functionalization of the Isoquinoline Core via Oxidative Radical Substitution
ChemistrySelect, Volume 11, Issue 21, 4 June 2026.The isoquinoline ring can be easily functionalized at C‐4 through a radical‐oxidative substitution process. The resulting products can be readily cyclized under basic conditions, facilitating the construction of pyranones fused to the isoquinoline scaffold. ABSTRACTIn this work, we report a straightforward synthetic procedure that enables the selective

ChemistrySelect, Volume 11, Issue 24, 25 June 2026.A practical SnCl4‐mediated Friedel–Crafts acylation of N‐tosylindoles provides regioselective access to diverse 3‐acylindoles with substrate scope across substituted indoles. The utility of this method is demonstrated in a concise total synthesis of the halogen‐rich marine natural product Breitfussin B.
