The Chemistry of Pyrrolic Compounds. LXVII. A New Demethyl Analog of DPEP (Deoxophylloerythroetioporphyrin)

Abstract

A new demethyl analogue of DPEP, present as a nickel(II) complex in the Julia Creek oil shale deposit of North Queensland, has been shown by ring synthesis to lack a methyl group in ring A. This is now the third demethyl analogue of DPEP to be identified.
