Abstract

β-Acetylporphyrins (e.g. 20, 35, 39) have been treated with Vilsmeier complex (POCl3-DMF) to afford β-(1-chloro-2-formylvinyl)porphyrins (23, 36, 41); with an excess of KOH in methanol these compounds were transformed into the corresponding alkynylporphyrins (17, 37, 38). The bis-alkynyl-porphyrin 17 was transformed into the corresponding hemin 25 by treatment with iron(II) chloride.
