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).
