Abstract
A mixture of acetic and
sulfuric acids converts haematoporphyrin into a complex mixture of porphyrins
of which the main product has been characterized as the diacetate (1g). Other
compounds identified in the reaction mixture were the known vinylporphyrins (1b-d),
(1h) and (li) and the isomeric monoacetoxyethyl(monohydroxyethyl)porphyrins
(11) and (1m). Analysis of the reaction mixture was complicated by the presence
of 1'-ethoxyethyl derivatives (1e) or (1f), (1j) and (1k)which presumably arose
by solvolysis of the corresponding acetate with ethanol present in the chloroform
used for the chromatographic separation.
