Ring Expansion of Benzothiaselenazole-1-oxides via Five-Membered Selenonium Ion-Mediated Alkene Insertion into Se–N Bonds

Abstract Ring expansion of heterocyclic frameworks provides an efficient approach to structurally diverse bioactive molecules, yet such transformations of organoselenium heterocycles remain largely unexplored. Herein, we report a calcium-catalyzed insertion of alkenes into the Se...
