Route to formyl-porphyrins

A method of making a 5-formylporphyrin, comprises the steps of: condensing a 5-acetaldipyrromethane with a dipyrromethane-1,9-dicarbinol to produce a porphyrin having an acetal group substituted thereon at the 5 position; and then hydrolyzing said porphyr

A new route to meso-formyl porphyrins

Prior syntheses of porphyrins bearing meso-formyl groups have generally employed the Vilsmeier formylation of an acid-resistant copper or nickel porphyrin. A new approach for the synthesis of free base porphyrins bearing one or two (cis or trans) meso-for
