Regio‐ and Diastereoselective Bisfunctionalization of C60 and Enantioselective Synthesis of a C60 Derivative with a Chiral Addition Pattern

A versatile and simple method provides access to covalent bisadducts of C60 with high regio- and diastereo-selectivity. Starting from optically pure bis(malonate) derivatives and C60, a double Bingel reaction afforded optically active cis-3 bisadducts (ee > 97%), whose chirality results exclusively from the addition pattern.
