Abstract
Reaction of N-lithioethylenediamine on the 11-membered monocyclic sesquiterpenoids zerumbone (I) and zerumbol (II) has been studied. Zerumbone undergoes polymerization in the presence of the reagent whereas zerumbol via transannular cyclization-oxidation is converted to the bicyclic ketone, 2-keto-Δ 5;6,4;11-bicyclo (6:3:0) undecane (VII). Its structure has been rigorously established by chemical degradation and spectral studies.
