A reliable synthesis of porphyrins with five-membered exocyclic rings from b-bilenes has been developed. This methodology has been applied to the first total synthesis of the porphyrin mineral abelsonite, as well as the widespread petroporphyrin deoxophyl

The synthesis of the porphyrins (2c-j) has been achieved by the oxidative cyclization of appropriately substituted biladienes-ac.The availability of authentic material has allowed the finalization of the structure of a series of aetiotype fossil porphyrins which vary in substitution pattern at positions 3 and 13.All combinations of H, Me and Et at these positions have now been isolated from natural sources.This points to a common precursor, possibly a divinylporphyrin, and strengthens the belief that the chlorophylls are the prime source of the petroporphyrins.A vinyl group, or a close derivative, is found at position 3 of all chlorophylls while fragmentation of the ubiquitous isocyclic ring of the chlorophylls could yield the vinyl group at position 13.
