Abstract

Starting from allo‐cyclogeranic acid, 3‐methyl‐4‐allo‐cyclogeranylbut‐2‐ene‐oic acid has been prepared. This monocyclic compound has been converted into a bicyclic isomer, for which a spiroeyclic structure is assigned. It represents a further new type of synthetic bicyclic sesquiterpenes.
