title: Unprecedented 1,3-dipolar cycloaddition: from 1,4,5,8-naphthalene bisimides to a new heterocyclic skeleton.
abstract: 1,4,5,8-Naphthalene bisimides react as dipolarophiles with in situ formed azomethine ylides. Double 1,3-dipolar cycloaddition is followed by unique ring rearrangement and leads to the formation of two six-membered rings. The formation of hexacyclic products is rationalized based on DFT calculations.
