We have synthesized and isolated two C2-symmetric enantiomerically pure trisadducts of C60 with an inherently chiral trans-3,trans-3,trans-3 addition pattern with the aid of an enantiopure cyclo-tris-malonate tether. An unexpected stereoisomerism was observed which was attributed to the spatial arrangement of spacers in the tether.
