Popis: | Both enantiomers of the key intermediate, 2-benzyl-5-oxo-tetrahydro-furan-2-carboxylic acid were obtained by asymmetric oxidation of 3-benzyl-2-hydroxy-2-cyclopenten-1-one with an ee ⩾96%, using the tartaric ester/Ti(O i Pr) 4 / t -BuOOH complex, and transformed to the corresponding 4′-substituted nucleoside analogues with up to 61% overall yield. |
