An efficient synthesis of the two diastereomeric tetrakisfulleroids 14a and 14b is described starting from the readily accessible trans-1 bis-Diels-Alder adduct 12. The challenging issue of generating multiple bond scissions regiochemically within the fullerene framework, here as [5,6] open systems (fulleroids), is simplified into performing two separate regiocontrol phases. The initial bisadduct 12
