Helical chirality induction of expanded porphyrin analogues

Expanded porphyrin analogues with unique figure-eight conformation were prepared by way of useful pyrrole intermediates such as bis(azafulvene)s and 2-borylpyrrole. Supramolecular chirogenesis of cyclooctapyrrole O1 with 32π-cycloconjugation was successfu

Synthesis of bis(azafulvene)s by dehydration of hydroxymethylpyrrole derivatives

Bis(azafulvene) was isolated in 55% yield by the reaction of 4 equivalents of phenyllithium with 5,5′-diformyl-3,3′,4,4′-tetraethyl-2, 2′-bipyrrole followed by quenching with acetic anhydride. Unstable bis(azafulvene)s were obtained in much higher yields

A facile and efficient method for the preparation of new meso-arylbisdipyrrins

The phosphorous oxytrichloride mediated condensation of diaroylbipyrroles 5a-e with the α-unsubstituted pyrrole 2 was found to produce diarylbisdipyrrins 6a-e in good to excellent yields. The method is compatible with a series of functional groups on the aryl substituents. This paper reports preparative and spectroscopic details for five new diarylbisdipyrrins as well as those for one meso-unsubstituted alkylbisdipyrrin.
