| 摘 要： | Regioselective ring-opening reactions of 1,2-epoxides with ArSeH catalyzed by Ti（O^tPr）4 under solvent-free conditions were investigated. A variety of β-hydroxyselenides were obtained in excellent yields of 90%-97% and regioselectivities by a simple, atom economic and environment-friendly procedure. Several N-tosyl- 1,3-oxazolidin-2-ones were prepared starting from the corresponding 1,2-epoxides and ArSeH by a one-pot three-step procedure.

| Abstract: | Regioselective ring‐opening reactions of 1,2‐epoxides with ArSeH catalyzed by Ti(OiPr)4 under solvent‐free conditions were investigated. A variety of β‐hydroxyselenides were obtained in excellent yields of 90%–97% and regioselectivities by a simple, atom economic and environment‐friendly procedure. Several N‐tosyl‐1,3‐oxazolidin‐ 2‐ones were prepared starting from the corresponding 1,2‐epoxides and ArSeH by a one‐pot three‐step procedure. |
