Different reactivity of the double bonds of the starting diene 1 is a precondition for its cyclization in the reaction with Hg(OAc) 2 in the presence of CaO and MeOH; reduction with NaBH 4 then affords 2 . The radical 3 is presumed to be an intermediate in the cyclization. Compound 2 is of interest as a starting material for the synthesis of iridoids as well as for the construction of di‐ and triquinane frameworks.
