Synthesis of the C30 Desethylaetioporphyrin from Petroleum

The four desethyl analogues of aetioporphyrin-III have been synthesised by the biladiene route; h.p.l.c. comparisons showed that the desethylaetioporphyrin obtained from petroleum is the c-ring isomer (3c).

Synthesis and Characterisation of the C30-De-ethylaetioporphyrin Present in Petroleum

The four de-ethyl analogues of the relatively ubiquitous and biogenetically significant petroporphyrin aetioporphyrin III (3a-d) have been synthesized utilising the ac-biladiene route.A reversed-phase HPLC method of separating a mixture of the four synthe
