Description

ABSTRACT:
A process for producing 3-oxo-6-formyl-2-oxabicyclo[3.3.0]-6-octene useful as an intermediate for producing prostaglandins, via a few steps from raw materials which can be relatively easily prepared. The process comprises subjecting 2,2-dimethyl-1,3-dioxin-4-one and cis-2-cyclopenten-1,4-diol to addition reaction in a solvent, preferably under a photo-irradiation, removing the solvent from the reaction mixture, adding water to the resulting adducts and reacting the resulting mixture on heating.
