A key intermediate for the synthesis of (+)-grandisol, (4aR, 6aR)-4a-methyl-2-oxabicyclo[4.2.0]octan-1-one, was synthesized starting from (-)-quinic acid as the chiral source.

The synthesis of enantiomerically pure (+)-grandisol has been achieved from an enzymically generated chiral synthon. The synthesis is an efficient one, the yield of optically pure material being 12% up to the penultimate step and 3% overall.
