Synthesis of Enantiopure T-Symmetrical [6:0]-Hexakis Adducts of C60 Equipped with 1,2-Glycol Substituted cyclo-Monomalonate Addends.

The synthesis of T-symmetrical [6:0]-hexakis adducts of C60 bearing enantiopure cyclo-monomalonate addends equipped with 1,2-glycol groups masked as isopropylidene acetals is presented. The deprotection of the acetals afforded functional fullerene building blocks bearing six 1,2-glycol moieties in an octahedral geometry as connection sites with appropriate linear organic spacers targeting 3D chiral extended networks with cubic building units. Evaluation of the experimental results revealed the advantageous synthetic accessibility to hexakis adduct (-)-9 which carries six homochiral C12 cyclo-monomalonate addends.
