Published: April 2022

A barley diterpene synthase (HvKSL4) was found to produce (14)-cleistantha-8,12-diene (). Formation of the nearly planar cyclohexa-1,4-diene configuration leaves the ring poised for aromatization, but necessitates a deceptively complicated series of rearrangements steered through a complex energetic landscape, as elucidated here through quantum chemical calculations and labeling studies.
