The Fragmentation of 2,3-Dihydroisothiazol-3-one 1,1-Dioxide Derivatives: A Novel Cheletropic Process

CHIMIA, 1992
Adducts obtained by 1,3-dipolar cycloadditions to 2,3-dihydroisothiazol-3-one 1,1-dioxides are inclined to undergo a cheletropic process, by which the newly formed heterocyclic part undergoes aromatization, while SO2 is extruded and an ...

Rh(III)‐Catalyzed Cascade C─H Activation/[4 + 1] Annulation: A Direct Route to Benzofuran‐‍Fused Succinimides From Aromatic Acids and 3‐Methylmaleimides

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Benzofuran‐linked succinimides have been developed from aromatic carbocyclic and heterocyclic acids, as well as 3‐methylmaleimides, using a Rh(III)‐catalyzed C─H activation and [4+1] annulation cascade reaction. A Rh(III)‐catalyzed [4 + 1] cyclization of aromatic carbocyclic/heterocyclic acids with 3‐methylmaleimides has been developed, providing an ...

Imidazo[1,2‐b]Pyrazole‐1,2,4‐oxadiazole Linked 1,2,3‐Triazoles: Synthesis, Antibacterial, Biofilm, and In Silico Studies

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
A collection of innovative imidazo[1,2‐b]pyrazole–1,2,4‐oxadiazole–1,2,3‐triazole hybrids was conceived via the molecular hybridization of bioactive pharmacophores and produced via a CuAAC methodology. The synthesized compounds exhibited strong antibacterial and antibiofilm properties against gram‐positive bacteria.
