Mc. Carreno et al., PI-FACIAL DIASTEREOSELECTION IN DIELS-ALDER REACTIONS OF (R)-4-[(P-TOLYLSULFINYL)METHYL]QUINOLS, Journal of organic chemistry, 62(26), 1997, pp. 9128-9137
Diels-Alder reactions of a range of -4-[(p-tolylsulfinyl)methyl]-2,5-c
yclohexadienones with cyclopentadiene and 1,3-pentadiene proceed in a
total pi-facial diastereoselective manner from the C-4 OH side. Ab ini
tio calculations at the RHF/6-31G theory level provide data on transi
tion-state energies for cycloadditions with cyclopentadiene in full ag
reement with the experimental results.
