New and simple protocols are described for the conversion of the enzymatically-derived and enantiomerically pure cis-1,2-dihydrocatechol 7 (X = I) and its 6-methylated derivative into either antipodal form of compounds embodying the tricyclic frameworks of terpenoids 1–6. Key steps include intramolecular Diels–Alder (IMDA) and (in some cases) singlet or triplet-based photochemical processes.
