Stereodivergent syntheses of cis/trans pyrrolidino[3,4:1,2]fullerenes and endo/exo pyrrolidines are reported with high enantioselectivity levels. Fullerenes are revealed as a useful benchmark to develop suitable catalysts to control the stereochemical outcome and to shed light on the mechanism involved in the related 1,3-dipolar cycloaddition.
