Studies on oxidopyrylium [5 + 2] cycloadditions: Toward a general synthetic route to the C12-hydroxy daphnetoxins

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.
