Hartrampf, Felix W. W. published the artcileA Conia-Ene-Type Cyclization under Basic Conditions Enables an Efficient Synthesis of (-)-Lycoposerramine R, COA of Formula: C7H13BrSi, the publication is Angewandte Chemie, International Edition (2017), 56(3), 893-896, database is CAplus and MEDLINE.
An enantioselective total synthesis of the Lycopodium alkaloid lycoposerramine R (I) is presented. It relies on a base-mediated cyclization that resembles the Conia-ene reaction of ynones and gold-catalyzed variants thereof. Thus, hydrindanones and other functionalized ring systems bearing an exocyclic alkene can be rapidly accessed at room temperature without noble metal catalysis or substrate preactivation.
