acetonide moieties led to the synthesis and successful column chromatographic isolation of the enantiomerically pure f,sC and f,sA bisadducts with the inherently chiral trans-3 addition pattern. Acidic deprotection of the acetonide groups gave access to novel chiral fullerene compounds which combine the inherent chirality of the fullerene core with the functional glycol groups located on the tether.
