Enantiocontrolled synthesis of quaternary carbon centers via anionic oxy-cope rearrengement: An efficient synthesis of (+)-dihydromayurone

(+)-Dihydromayurone (1) was enantioselectively synthesized from β-cyclocitral (7). The key step in the synthesis involved anionic oxy-Cope of allylic alcohol 6 to aldehyde 5. Efficient transfer of chirality from the secondary allylic alcohol center to the quaternary carbon center was observed vai chairlike transition state with the equatorial oxyanionic bond.
