概要 The total syntheses of (+)​- and (-​)​-​1,​3,​4,​5-​tetragalloylapiitol were achieved in seven steps from D- and L-​ribose, resp. By comparing the optical rotations of both enantiomers with those of the natural product, the abs. configuration at C-​3 in the naturally occurring 1,​3,​4,​5-​tetragalloylapiitol has been revised to R. The abs. configurations at C-​3 in the synthetic (+)​- and (-​)​-​1,​3,​4,​5-​tetragalloylapiitol were further confirmed by the CD exciton chirality method.
