Abstract
The total syntheses of (+)- and (â)-1,3,4,5-tetragalloylapiitol were achieved in seven steps from d- and l-ribose, respectively. By comparing the optical rotations of both enantiomers with those of the natural product, the absolute configuration at C-3 in the naturally occurring 1,3,4,5-tetragalloylapiitol has been revised to R. The absolute configurations at C-3 in the synthetic (+)- and (â)-1,3,4,5-tetragalloylapiitol were further confirmed by the circular dichroism exciton chirality method.
