A five-step totalsynthesis of (±)-verrubenzospirolactone has been achieved using a biomimetic, intramolecular Diels–Alder reaction of a 2H-chromene to form two rings and four stereocenters in the final step. This Diels–Alder reaction occurs spontaneously at 30 °C “on-water”, and thus suggests that it is likely to be non-enzymatic in nature. The structure of (±)-verrubenzospirolactone was also used
