Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Organocatalysis and fullerenes merge</bold>: The first asymmetric organocatalytic synthesis by phosphine‐catalyzed [3+2] cycloaddition of allenoates onto [60]fullerene that occurs under mild conditions giving rise to enantiomerically pure carbocyclic fullerene derivatives is reported. X‐ray analysis of a cyclopenteno[60]fullerene has allowed the assignment of the absolute configuration of the new stereocenter. Furthermore, the sector rule previously used to assign the chirality in [60]fullerenes has been corrected in the light of these new experimental findings.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1zsxjht9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
