The catalytic epoxidation of olefins 4-7 catalyzed by synthetic metalloporphyrin analogues [FeL₃] 3 associated with molecular oxygen in the presence of an electron source (isobutyraldehyde) is described. Furthermore, it is shown, that 4-substituted 1,4-dihydropyridines 12 can be dehydrogenated and dealkylated, respectively, by the same system. The analogy to cytochrome P-450 is obvious.
