Replacement of a single pyrrole ring by a cyclopentadiene fragment appears to be a compelling strategy for the creation of true carbaporphyrins, which can be regarded as fundamental extensions of the classical porphyrinic motif. In their Communication on page 4885 ff., L. Latos-Grażyński and co-workers describe the rational approach that allowed incorporation of an unsubstituted cyclopentadiene instead of a pyrrole ring in a heteroporphyrin framework to form 21-carbathiaporphyrin, the first meso-substituted true carbaporphyrinoid.
