Ruthenium-Catalyzed Transfer Oxygenative [2 + 2 + 1] Cycloaddition of Silyldiynes Using Nitrones as Adjustable Oxygen Atom Donors. Synthesis of Bicyclic 2‑Silylfurans

The first example of the Ru-catalyzed transfer oxygenative [2 + 2 + 1] cycloaddition of silyldiynes to produce bicyclic 2-silylfurans is described. This cyclization process was realized using nitrones as readily available and adjustable oxygen atom donors. The bicyclic silylfuran products could be u...

Summary:The first example of the Ru-catalyzed transfer oxygenative [2 + 2 + 1] cycloaddition of silyldiynes to produce bicyclic 2-silylfurans is described. This cyclization process was realized using nitrones as readily available and adjustable oxygen atom donors. The bicyclic silylfuran products could be used as platforms for a diverse range of functionalized furans.
