Anomalous cyclization of 1,19-dimethyl-a, c-biladienes: Direct synthesis of meso-aminoporphyrin derivatives
Treatment of the a, c-biladiene (3) with copper(II) acetate in DMF leads, after demetallation, to expected porphyrin (4) along with the meso-N, N-dimethylaminoporphyrin (5) in which the new meso carbon is derived from the carbonyl carbon of the DMF solvent. © 1985, Taylor & Francis Group, LLC.
