π-Facial Diastereoselection in Diels−Alder Reactions of (R)-4-[(p-Tolylsulfinyl)methyl]quinols
摘要:
Diels-Alder reactions of a range of (R)-4-hydroxy-4-[(p-tolylsulfinyl)methyl]-2,5-cyclohexadienones with cyclopentadiene and 1,3-pentadiene proceed in a total pi-facial diastereoselective manner from the C-4 OH side. Ab initio calculations at the RHF/6-31G* theory level provide data on transition-state energies for cycloadditions with cyclopentadiene in full agreement with the experimental results.
