The new and efficient synthesis of a heptose moiety of spicamycin

The new and efficient synthesis of 7-O-acetyl-4-azido-2,3,6-tri-O-benzyl-4-deoxy-L-glycero-α-L-manno- heptopyranosyl acetate (5), a key intermediate for the synthesis of novel anti-cancer antibiotic, spicamycin (1), starting from D-ribose is described.

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.
