Abstract
The disclosure relates to a series of novel prostaglandin intermediates, the preparation of which in sequence constitutes a novel process for the manufacture of known diol intermediates, for example 2,3,3a.beta.,6a.beta.-tetrahydro-5.alpha.-hydroxy-4.beta.-(3-hydroxyoct-1- trans-enyl)-2-oxocyclopenteno[b]furan, from the readily available norbornadiene, said process comprising fewer and more easily operable stages than previously known processes for the manufacture of said diol intermediates.
