  Studies on Oxidopyrylium [5 + 2] Cycloadditions:  Toward a General Synthetic Route to the C12-Hydroxy Daphnetoxins

  摘要：

  [GRAPHICS]12-Hydroxydaphnetoxins, members of the structurally fascinating daphnane diterpene family, exhibit a wide range of significant biological activities. A general route to the BC-ring system of 12-hydroxy daphnetoxins is reported based on D-ribose. Depending on the choice of protecting groups and solvent, the oxidopyrylium-alkene [5+2] cycloaddition originating from A provides cycloadduct diastereomer B or C with good to excellent selectivity.
