Construction of β-Acetoxy or β-Hydroxyl Disulfides via Highly Regioselective Ring-Opening of Epoxides with Acetyl Masked Disulfide Nucleophiles

Copper-Catalyzed Tandem Cyclization/Chalcogenation with Elemental S8/Se: Concise Synthesis of 3-(β-Hydroxychalcogen)benzofurans

“…β-Hydroxy chalcogenides are essential structural units owing to their extensive use in the synthesis of core molecules, such as allylic alcohols, olefins, and vinyl sulfurs/selenides, as well as due to their abundance in pharmacologically and biologically active molecules . According to reports, the synthesis of β-hydroxy chalcogenides relies on the ring-opening step of epoxides with chalcogenide reagents (RSH, RSSR, RSeH, RSeSeR, etc.)…”
