Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Similar yet different</bold>: A one‐step regio‐ and diastereoselective synthesis of three new bis(pyrrolidine)[60]fullerenes, one <italic>cis</italic>‐1 and two unprecedented <italic>cis</italic>‐2 diastereoisomers, is reported (see scheme). The compounds are easily purified using simple chromatographic techniques, and were fully characterized by spectroscopic techniques and X‐ray crystallography. A mechanism for the isomeric conversion observed is proposed.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t7b030d" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
