The Bingel addition of a trimalonate derived from a chiral, cyclotriveratrylene (CTV)-based tripodal tether to C60 was reinvestigated. The present use of enantiomerically pure (P)and (M)-configured CTV units in the tether allowed the isolation of a total of four enantiomerically pure C3-symmetric trisadducts of [60]fullerene (two from each CTV enantiomer). With the support of NMR and UV/Vis spectroscopy
