Asymmetric oxidation of methyl phenyl selenide (3), under anhydrous conditions, by chiral 2-sulfonyloxaziridines, 1–2, gives optically active methyl phenyl selenoxide (8.1–9.3% ee). The stereochemistry of the selenoxide is determined by the configuration of the oxaziridine three membered ring with non-bonded steric interactions responsible for the chiral recognition. Asymmetric oxidation of E-phenyl

A visible‐light‐induced method was developed to synthesize selenylated cyclic boronic esters through intermolecular oxyselenenylation. This method can be performed under additive‐free and photocatalyst‐free conditions and generates potentially pharmaceutically useful heterocycles. A plausible reaction mechanism was proposed based on several control experiments and previous reports.
