Acid-catalyzed [3+3] condensation reactions of two hitherto unknown tripyrrane moieties with pentafluorobenzaldehyde has led to the formation of new generation heteroannulene (4.1.4.1) and mutant heteroannulene (1.1.1.1.1.1). Inclusion of local π-aromatic sextets, namely the N-methyl pyrrole rings through β,β-linkages and α,β-linkages, has led to the isolation of first ever heteroannulenes cross-conjugated at four points and two points respectively within the macrocycles.

A concise and convenient synthetic methodology leading to an unambiguous isolation of two hitherto unknown highly stable single conformers of meso-aryl substituted unorthodox 5,10-porphodimethenes has been developed by the inclusion of N-methyl pyrrole units with α,β and β,β-linkages into the core of heterocyclic macrocycles.
M?bius Aromatic Core-Modified Heterocyclic [20] Macrocycles (4.1.1) with a Protruding N-Methyl Pyrrole Ring

Herein, we report the first synthesis of an unorthodox tripyrrane moiety from the regioselective β-benzoylation of pyrrole and the acid-catalyzed condensation of the desired precursors. A [3+1] Mac Donald type condensation strategy for this tripyrrane has led to the exclusive isolation of two hitherto-unknown aromatic [20] heterocyclic macrocycles (4.1.1).
