Extremely mild (no metal Lewis acid catalyst, ambient temperature) and experimentally simple (no high-pressure apparatus needed) conditions were established for the Diels–Alderreaction between sterically demanding 1,3,3-trisubstituted-2-vinylcyclohexenes and non-symmetrically substituted quinones. This allowed for the successful implementation of a highly convergent strategy to the cassane-type furanoditerpenoid
