Abstract

A novel sesquiterpene, isolated as the putative sex pheromone of a stink bug (Tynacantha marginata Dallas) and proposed to have an unprecedented carbon framework, was synthesized as its racemate by using an intramolecular double Michael cyclization as the key step. Comparison of the spectral data of the synthetic sample with those of the natural material confirmed the proposed structure.
