Iridoid Sex Pheromone Biosynthesis in Aphids Mimics Iridoid‐Producing Plants [PDF]

Chemistry – A European Journal, 2021
AbstractBiosynthesis of (1R,4aS,7S,7aR)‐nepetalactol (1) and (4aS,7S,7aR)‐nepetalactone (2) in plants involves iridoid synthase (ISY), an atypical reductive cyclase that catalyses the reduction of 8‐oxogeranial into the reactive enol of (S)‐8‐oxocitronellal, and cyclization of this enol intermediate, either non‐enzymatically or by a nepetalactol ...
