stereodivergent total synthesis of the Δ13-9-isofurans has been developed. The four core substituted tetrahydrofurans were prepared by the Sharpless asymmetric epoxidation and Sharpless asymmetric dihydroxylation followed by cascade cyclization. The relative configuration at C-8 was inverted by oxidation followed by immediate L-Selectride reduction. The relative configuration of the C-15 diastereomers was

The synthesis of the title compounds is described. It is shown that β-nitro ketals are versatile intermediates for the synthesis of prostaglandin-type C-13 – C-20 side-chains.
