Chemistry – A European Journal, EarlyView.The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies
European Journal of Organic Chemistry, EarlyView.A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.
