The optically active tetracycle (6) with two trans-fused angular methyl groups is constructed from tiglic aldehyde and (S)-carvone in 9 steps involving a stereocontrolled aldol reaction and an endo-selective intramolecular Diels-Alder (IMDA) reaction.

The tricycle (5) with two trans-fused angular methyl groups is constructed from tiglic aldehyde and (S)-carvone involving a stereocontrolled aldol reaction and an endo-selective intramolecular Diels-Alder (IMDA) reaction; the stereochemistry was established by an X-ray study.
