Application of chemical P-450 model systems to studies on drug metabolism. Part X. Novel hydroxylactonization of γ,δ- and β,γ- unsaturated carboxylic acids with an iron porphyrin–iodosylbenzene system
The oxidative hydroxylactonization of γ,δ- and β,γ-unsaturated carboxylic acids by a chemical cytochromeP-450model and rat liver microsomal systems has been investigated. In the chemical system using meso-tetrakis(2,6-dichlorphenyl)porphyrin iron chloride [Fe(TDCIPP)Cl] with iodosylbenzene (PhIO), γ,δ-unsaturated carboxylic acids have been converted into δ-hydroxy-γ-lactones in high yield and with
