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...

Umpolung at the meta ‐Positions of Oxazino‐Pyridines Enabling Nucleophilic Pyridine Functionalization

ABSTRACT Selective C─H functionalization of azines is of paramount importance to synthetic and medicinal chemistry. However, nucleophilic functionalization at meta‐ position of pyridines has remained elusive because of the intrinsic polarity mismatch. In this study, we report a m...
