Dipyrromethanes constitute a widely known and relevant class of useful synthetic building blocks in the chemistry of several high-value pyrrolic macrocycles, e.g. calixpyrroles, porphyrins, chlorins, corroles, saphyrins, and dipyrromethene compounds, such as boron dipyrrins (BODIPYs) and various related transition metal coordination complexes. A bibliographic review on the synthesis of dipyrromethane scaffolds surveying the past six years (2014-2019) is herein provided. Classic synthetic approaches employing the acid-catalyzed condensation of pyrroles and aldehydes or ketones, as well as modern strategies that allow the synthesis of original dipyrromethane structures with novel substitution patterns are presented.
