A short synthesis of the title compound, 16, from d-ribonolactone is described. Two alternative approaches differing in the timing of the C C double bond creation are used to prepare some chiral derivatives of 16.(−)-Ranunculin, a glycoside present in Ranunculaceae, has been synthesized for the first time.
