The dynamic kinetic resolution of 6-hydroxypyranones I [R1 = H, R2 = H, Me, Et, n-Pr, i-Pr, H2C:CHCH2CH2, t-BuSiMe2OCH2; R1 = R2 = Me, Et, cyclopropyl, Ph; R1R2 = (CH2)3, CH2OCH2, etc.; R3 = H, Me, PhCH2CH2; R4 = H, Me, Et, PhCH2CH2, PhCH2OCH2; R3R4 = (CH2)3, (CH2)4] with enals R5CH:CHCHO (R5 = cyclohexyl, Ph, 4-MeOC6H4, etc.) or alkynals R5CCCHO (R5 = 4-MeOC6H4, cyclopentyl, n-octyl, etc.) through an asym. redox esterification was catalyzed by a chiral N-heterocyclic carbene. The resulting esters II were obtained in good to high yields and with high levels of enantio- and diastereocontrol. The reaction products were further derivatized to obtain functionalized sugar derivatives and natural products.
