The isolation and structural determination (n.m.r., n.O.e., synthesis) of a C33 member of the DPEP series from Boscan crude oil indicates that total reduction of the propionic side-chain of a precursor chlorophyll may occur during the processes leading to oil formation.

Zinc(II) porphyrins bearing unsubstituted β positions can be mercurated at the β position and at an adjacent meso position.Palladium / olefin reactions with the dimercurated porphyrins produce products possessing a five-membered isocyclic ring bridging the β and meso positions and resembling that found in chlorophyll derivatives.With use of this methodology, novel syntheses of deoxophylloerythroetioporphyrin (2) and deoxophylloerythrin methyl ester (3), two degradation products of chlorophyll, are described.
