After iridoid synthase reduces 8-oxogeranial (2) using nicotinamide adenine dinucleotide phosphate (NADPH) as hydride (H –) donor, enol or enolate intermediate 3 is formed (Figure 1 B).The existence of reaction intermediate 3 is supported by the identification of reduced aldehyde 4, the more stable tautomer of 3, as a … WebBiosynthesis of Iridoids and Secoiridoids. Research on iridoids began with the discovery of asperuloside (1) (an iridoid glucoside) in 1848 and gentiopicroside (2) (a secoiridoid glucoside) in 1862. However, it was only in the late 1950’s that the structures of the compounds of this series began to be elucidated.
