The conditions for the porphyrin synthesis by condensation of α-unsubstituted dipyrromethanes and ortho-formic ester in the presence of organic acids are investigated. The optimal reaction conditions are found, and a series of β- and meso-substituted porphyrins is synthesized. The methods of the α-unsubstituted dipyrromethanes synthesis from pyrroles obtained by Knorr method are designed. The synthesized compounds were characterized by spectral methods.
