    • Bioinspired Cobalt-Catalysis Enables Generation of Nucleophilic Radicals from Oxetanes 

      Potrząsaj, Aleksandra; Ociepa, Michał; Chaładaj, Wojciech; Gryko, Dorota (American Chemical Society, 2022-03-25)
      Oxetanes are valuable building blocks due to their well-explored propensity to undergo ring-opening reactions with nucleophiles. However, their application as precursors of radical species is still elusive. Herein, we ...
    • Tandem Pd-Catalyzed Cyclization/Coupling of Non-Terminal Acetylenic Activated Methylenes with (Hetero)Aryl Bromides 

      Błocka, Aleksandra; Chaładaj, Wojciech (MDPI, 2022)
      We report a new method for a tandem Pd-catalyzed intramolecular addition of active methylene compounds to internal alkynes followed by coupling with aryl and heteroaryl bromides. Highly substituted vinylidenecyclopentanes ...
    • Unprecedented 1,2-Aryl Shift Accompanying Double Alkyne Benzannulation 

      Sanil, Gana; Krzeszewski, Maciej; Chaładaj, Wojciech; Danikiewicz, Witold; Knysh, Iryna; Dobrzycki, Łukasz; Staszewska-Krajewska, Olga; Cyrański, Michał; Jacquemin, Denis; Gryko, Daniel T. (Wiley, 2023)
      The tandem intramolecular hydroarylation of alkynes accompanied by a 1,2-aryl shift is described. Harnessing the unique electron-rich character of 1,4-dihydropyrrolo[3,2-b]pyrrole scaffold, we demonstrate that the ...
    • UV Light Is No Longer Required for the Photoactivation of 1,3,4- Oxadiazolines 

      Orłowska, Katarzyna; Santiago, João V.; Krajewski, Piotr; Kisiel, Kacper; Deperasińska, Irena; Zawada, Katarzyna; Chaładaj, Wojciech; Gryko, Dorota (American Chemical Society, 2023)
      Carbenes play a key role in a plethora of organic transformations. Although stabilized diazo carbonyl compounds predominate as a source of electrophilic carbenes, the hazardous nature of nonstabilized analogues calls for ...
