α′-position with the ω-chain aldehydes followed by dehydration to produce the title compounds. In a similar manner, 5-dehydro compounds (acetylene analogues) were synthesized successfully. In addition, palladium-catalyzed reaction of 4-cyclopentene-1,3-diol monoacetate with methyl malonate, the first step of the synthesis, was improved to afford the product in high yield by using t-BuOK or LDA in place

Δ12-Prostaglandin J family is recently discovered and has potent anticancer activity. Concise syntheses of four Δ12-prostaglandin Jnaturalproducts (7-8 steps in the longest linear sequences) are reported, enabled by convergent stereoretentive cross-metathesis. Exceptional control of alkene geometry was achieved through stereoretention.

This invention relates generally to the synthesis of Δ12-Prostaglandin J product using stereoretentive ruthenium olefin metathesis catalysts supported by dithiolate ligands. Δ12- Prostaglandin J products were generated with excellent selectivity (>99% Z) and in moderate to high/good yields (47% to 80% yield; 58% to 80% yield).
