The relative stereochemistry of the four stereocentres of spirolaxine 1 , a bioactive 6,5‐spiroacetal phthalide secondary metabolite, was determined through single‐crystal X‐ray analysis. Its absolute configuration was determined by circular dichroism; the experimental spectrum of spirolaxine is in good agreement with that evaluated by means of DeVoe coupled‐oscillator calculations.
