Published in 2021 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.1c06331

Abstract: A long-standing question in porphyrin chemistry is why pyrrole monomers selectively form tetrapyrrolic macrocycles, whereas the corresponding tripyrrolic macrocycles are never observed. Calix[3]pyrrole, a tripyrrolic porphyrinogen-like macrocycle bearing three sp3-carbon linkages, is a missing link… read more here.
