Iron(III)Porphinate/H2O2-Mediated Conversion of All-(E)-Retinol

The reaction of hydrogen peroxide with all-(E)-retinol (1) catalyzed by (meso-tetraphenylporphinato)iron(III) led to the formation of 4-hydroxyretinol (2), 4-oxoretinol (3), 5,8-epoxyretinol (4), 5,6-epoxyretinol (5), 3-dehydroretinol (6), all-(E)- and 12-(Z)-retroretinol (7/7a) as well as all-(E)- and 12-(Z)-anhydroretinol (8/8a) as major non-volatile products.The conversion products were characterized by comparison of their chromatographic (HPLC) and spectroscopic data (UV; MS; 1H and 13C NMR) with those of synthesized reference compounds.The observed product formation supports the hypothesis of a C4 centered radical as the key intermediate of all-(E)-retinol conversion. - Keywords: 5,6- and 5,8-Epoxyretinol, 4-Hydroxyretinol, 4-Oxoretinol, Retinol Conversion
