Fullerene Sugars: Preparation of Enantiomerically Pure, Spiro‐Linked <i>C</i>‐Glycosides of C₆₀

Abstract

“Sweetened buckyballs” are prepared in good yields. The C-glycosylated, uniform, enantiomerically pure C60 monoaddition products 1 (R = benzyl, pivaloyl) are differentiated not only by their chi-roptical properties, but also by the conformation of the glycosyl residue, which is dependent on its substituents.
